New in Apache Tomcat 10.1.0-M7 Alpha (Nov 16, 2021)

  • Catalina:
  • Code: Refactor HttpServlet so the default doHead() implementation now calls doGet() and relies on the container to ensure that the response body is not sent. The previous behaviour (wrapping the response) may be enabled per Servlet by setting the jakarta.servlet.http.legacyDoHead Servlet initialisation parameter to true. This aligns Tomcat with recent changes updates for Servlet 6.0 in the Jakarta Servlet specification project. (markt)
  • Add: Add support for setting generic attributes for session cookies. This aligns Apache Tomcat with recent changes in the Jakarta Servlet specification project. (markt)
  • Fix: Do not add a trailing / to a request URI during canonicalization. (markt)
  • Fix: Invalid byte sequences (typically in %nn form) in a request URi that are not valid for the given URI encoding now trigger a 400 response. (markt)
  • Fix: Ensure that a request URI starts with a /. (markt)
  • Add: Add a new Connector option, rejectSuspiciousURIs that will causes 'suspicious' (see the Servlet 6.0 specification) URIs to be rejected with a 400 response. (markt)
  • Fix: Improve robustness of JNDIRealm for exceptions occurring when getting the connection. Also add missing close when running into issues getting the passord of a user. (remm)
  • Docs: Add Javadoc comment which listeners must be nested whithin Server elements only. (michaelo)
  • Add: Add support for custom caching strategies for web application resources. This initial implementation allows control over whether or not a resource is cached. (markt)
  • Coyote:
  • Code: Improve performance of Connector shutdown - primarily to reduce the time it takes to run the test suite. (markt)
  • Add: #457: Add a toString() method to MimeHeader to aid debugging. (dblevins)
  • Jasper:
  • Update: Regenerate the EL parser using JavaCC 7.0.10. (markt)
  • Fix: Fix a bug that prevented the EL parser correctly parsing a literal Map that used variables rather than literals for both keys and values. (markt)
  • Update: Ensure that the getType() method of any ELResolver implementation returns null if either the ELResolver or the resolved property is read-only to align Tomcat with recent updates in the Jakarta EL specification project. (markt)
  • Fix: Implement an alternative solution to support the JSP page directive attribute isThreadSafe now that the SingleThreadModel interface has been removed from the Servlet API. The new approach synchronizes the service() method.
  • Add: Add experimental OpenSSL support through the Panama API incubating in Java 17, with support for OpenSSL 1.1+. This no longer requires tomcat-native or APR. Please refer to the openssl-java17 module for more details. (remm)
  • WebSocket:
  • Update: Add a new method ServerEndpointConfig.Configurator.getContainerDefaultConfigurator() to align with recent updates in the WebSocket specification project. (markt)

  • Correct a regression in the previous release in the HTTP/2 flow controlwindow management along with additional improvements to HTTP/2 flow control
  • Make the CorsFilter simpler to extend
  • To avoid unnecessary cache revalidation, do not add an HTTP Expires headerwhen setting adding an HTTP header of CacheControl: private

New in Apache Tomcat 8.5.69 (Jul 7, 2021)

  • Re-work the HTTP/2 overhead protection to reduce the likelihood offalse positives. Note that the default overheadCountFactor has changedfrom 1 to 10 and that the useful range is now 0 to ~20
  • Fix regressions in JSP compilation in the previous release
  • Improve HTTP header parsing to ignore empty elements in 1#tokenvalues, as per RFC 7230 section 7

New in Apache Tomcat 10.1.0-M2 Alpha (Jul 5, 2021)

  • Catalina:
  • Code: Refactor the RemoteIpValve to use the common utility method for list to comma separated string conversion. (markt)
  • Code: Refactor JNDIRealm$JNDIConnection so its fields are accessible to sub-classes of JNDIRealm. (markt)
  • Fix: Fix serialization warnings in UserDatabasePrincipal reported by SpotBugs. (markt)
  • Fix: 65397: Calls to ServletContext.getResourcePaths() no longer include symbolic links in the results unless allowLinking has been set to true. If a resource is skipped because of this change, a warning will be logged as this typically indicates a configuration issue. (markt)
  • Coyote:
  • Fix: 65368: Improve handling of clean closes of inbound TLS connections. Treat them the same way as clean closes of non-TLS connections rather than as unknown errors. (markt)
  • Fix: Modify the HTTP/2 connector not to sent small updates for stream flow control windows to the user agent as, depending on how the user agent is written, this may trigger small writes from the user agent that in turn trigger the overhead protection. Small updates for stream flow control windows are now combined with subsequent flow control window updates for that stream to ensure that all stream flow control window updates sent from Tomcat are larger than overheadWindowUpdateThreshold. (markt)
  • Add: Add additional debug logging to track the current state of the HTTP/2 overhead count that Tomcat uses to detect and close potentially malicious connections. (markt)
  • Update: Many HTTP/2 requests from browsers will trigger one overhead frame and one non-overhead frame. Change the overhead calculation so that a non-overhead frame reduces the current overhead count by 2 rather than 1. This means that, over time, the overhead count for a well-behaved connection will trend downwards. (markt)
  • Update: Change the initial HTTP/2 overhead count from -10 to -10 * overheadCountFactor. This means that, regardless of the value chosen for overheadCountFactor, when a connection opens 10 overhead frames in a row will be required to trigger the overhead protection. (markt)
  • Update: Increase the default overheadCountFactor from 1 to 10 and change the reduction in overhead count for a non-overhead frame from -2 to -20. This allows for a larger range (0-20) to be used for overheadCountFactor providing for finer-grained control. (markt)
  • Fix: Modify the parsing of HTTP header values that use the 1#token to ignore empty elements as per RFC 7230 section 7 instead of treating the presence of empty elements as an error. (markt)
  • Fix: Expand the unit tests for HttpServlet.doHead() and correct the flushing of the response buffer. The buffer used to behave as if it was one byte smaller than the configured size. The buffer was flushed (and the response committed if required) when the buffer was full. The buffer is now flushed (and the response committed if required) if the buffer is full and there is more data to write. (markt)
  • Fix: Fix an issue where concurrent HTTP/2 writes (or concurrent reads) to the same connection could hang and eventually timeout when async IO was enabled (it is enabled by default). (markt)
  • Jasper:
  • Fix: 65387: Correct a regression in the fix for 65124 and restore the local definition of out for tags that implement TryCatchFinally. (markt)
  • Fix: 65390: Correct a regression in the fix for 65124 and restore code that was removed in error leading to JSP compilation failures in some circumstances. (markt)
  • Update: Update to the Eclipse JDT compiler 4.20. (markt)
  • Add: Add support for specifying Java 17 (with the value 17) as the compiler source and/or compiler target for JSP compilation. If used with an Eclipse JDT compiler version that does not support these values, a warning will be logged and the latest supported version will used. (markt)
  • Fix: 65377: Update the Java code generation for JSPs not to use the boxed primitive constructors as they have been deprecated in Java 9 and marked for future removal in Java 16. valueOf() is now used instead. (markt)
  • WebSocket:
  • Code: Refactor the DigestAuthenticator to reuse a shared SecureRandom instance rather than create a new one to generate the cnonce if required. (markt)
  • Web applications:
  • Fix: 65385: Correct the link in the documentation web application the Maven Central repository. (markt)
  • Other:
  • Add: Use JSign to integrate the build script with the code signing service to enable release builds to be created on Linux as well as Windows. (markt)

  • Fix: 60087: Refactor the web resources handling to use the Tomcat specific war:file:... URL protocol to refer to WAR files and their contents rather than the standard jar:file:... form since some components of the JRE, such as JAR verification, give unexpected results when the standard form is used. A side-effect of the refactoring is that when using packed WARs, it is now possible to reference a WAR and/or specific JARs within a WAR in the security policy file used when running under a SecurityManager. (markt)

  • Coyote:
  • Add: Refactor the code that implements the requirement that a call to complete() or dispatch() made from a non-container thread before the container initiated thread that called startAsync() completes must be delayed until the container initiated thread has completed. Rather than implementing this by blocking the non-container thread, extend the internal state machine to track this.

  • Fix: Correct a regression in the fix for 58588 that removed the entire org.apache.juli package from the embedded JARs rendering them unusable.
  • Add: 59399: Add a new option to the Realm implementations that ship with Tomcat that allows the HTTP status code used for HTTP -> HTTPS redirects to be controlled per Realm.
  • Fix: 59708: Modify the LockOutRealm logic. Valid authentication attempts during the lock out period will no longer reset the lock out timer to zero.
  • Update: Change the default of the sessionCookiePathUsesTrailingSlash attribute of the Context element to false since the problems caused when a Servlet is mapped to /* are more significant than the security risk of not enabling this option by default.
  • Fix: Follow-up to 59655. Improve the documentation for configuring permitted cookie names. Patch provided by Kyohei Nakamura.
  • Fix: Do not attempt to start web resources during a web application's initialisation phase since the web application is not fully configured at that point and the web resources may not be correctly configured.

  • Jasper:
  • Fix: Improve error handling around user code prior to calling InstanceManager.destroy() to ensure that the method is executed.
  • WebSocket:
  • Code: Now the WebSocket implementation is not built directly on top of the Servlet API and can use Tomcat internals, there is no need for the dedicated WebSocket Executor. It has been replaced by the use of the Connector/Endpoint provided Executor.
  • Fix: Improve error handling around user code prior to calling InstanceManager.destroy() to ensure that the method is executed.
  • Web Applications:
  • Fix: Do not log an additional case of IOExceptions in the error handler for the Drawboard WebSocket example when the root cause is the client disconnecting since the logs add no value.
  • Fix: 59642: Mention the localDataSource in the DataSourceRealm section of the Realm How-To.
  • Fix: 59672: Update the security considerations page of the documentation web application to take account of the fact that the Manager and HostManager applications now have a RemoteAddrValve configured by default.
  • Fix: Follow-up to the fix for 59399. Ensure that the new attribute transportGuaranteeRedirectStatus is documented for all Realms. Also document the NullRealm and when it is automatically created for an Engine.

  • Coyote:
  • Remove accidentally committed debug code

New in Apache Tomcat 9.0.0 M7 (Jul 14, 2016)

  • Catalina:
  • Fix: RMI Target related memory leaks are avoidable which makes them an application bug that needs to be fixed rather than a JRE bug to work around. Therefore, start logging RMI Target related memory leaks on web application stop. Add an option that controls if the check for these leaks is made. Log a warning if running on Java 9 with this check enabled but without the command line option it requires.
  • Fix: Ensure NPE will not be thrown during deployment when scanning jar files without MANIFEST.MF file.
  • Code: Remove the clearReferencesStatic option from StandardContext. It was known to cause problems with some libraries (such as log4j) and was only linked to suspected memory leaks rather than known memory leaks. It had been disabled by default with no increase in the reports of memory leaks for some time.
  • Fix: 59604: Correct the assumption made in the URL decoding that the default platform encoding is always compatible with ISO-8859-1. This assumption is not always valid, e.g. on z/OS.

  • Fix: When an asynchronous request is processed by the AJP connector, ensure that request processing has fully completed before starting the next request.
  • Fix: Improve handling of HTTP/2 stream resets.
  • Add: 58750: The HTTP Server header is no longer set by default. A Server header may be configured by setting the server attribute on the Connector. A new Connector attribute, serverRemoveAppProvidedValues may be used to remove any Server header set by a web application.
  • Fix: 59564: Correct offset when reading into HTTP/2 input buffer that could cause problems reading request bodies.
  • Fix: Modify the handling of read/write timeouts so that the appropriate error handling (ReadListener.onError(), WriteListener.onError() or AsycnListener.onError()) is called.
  • Fix: If an async dispatch results in the completion of request processing, ensure that any remaining request body is swallowed before starting the processing of the next request else the remaining body may be read as the start of the next request leading to a 400 response.
  • Jasper:
  • Fix: 59567: Fix NPE scanning webapps for TLDs when an exploded JAR has an empty WEB-INF/classes/META-INF folder.
  • Fix: Fix a memory leak in the expression language implementation that caused the class loader of the first web application to use expressions to be pinned in memory.

  • WebSocket:
  • Fix: 59659: Fix possible memory leak in WebSocket handling of unexpected client disconnects.
  • Web applications:
  • Fix: 58891: Update the SSL how-to.
  • Extras:
  • Code: 58588: Remove the JULI extras package from the distribution. It was only useful for switching Tomcat's internal logging to log4j 1.2.x and that version of log4j is no longer supported. No additional Tomcat code is required if switching Tomcat's internal logging to log via log4j 2.x.
  • jdbc-pool:
  • Fix: Fix a memory leak with the pool cleaner thread that retained a reference to the web application class loader for the first web application to use a connection pool.
  • Other:
  • Update: Update the internal fork of Commons DBCP 2 to r1743696 (2.1.1 plus additional fixes).
  • Update: Update the internal fork of Commons Pool 2 to r1743697 (2.4.2 plus additional fixes).
  • Update: Update the internal fork of Commons File Upload to r1743698 (1.3.1 plus additional fixes).
  • Code: Use UTF-8 with a standard prolog for all XML files.
  • Fix: 58626: Add support for a new environment variable (USE_NOHUP) that causes nohup to be used when starting Tomcat. It is disabled by default except on HP-UX where it is enabled by default since it is required when starting Tomcat at boot on HP-UX.

  • Fix: 59310: Do not add a Content-Length: 0 header for custom responses to HEAD requests that do not set a Content-Length value.
  • Fix: When normalizing paths, improve the handling when paths end with /. or /.. and ensure that input and output are consistent with respect to whether or not they end with /.
  • Fix: 59317: Ensure that HttpServletRequest.getRequestURI() returns an encoded URI rather than a decoded URI after a dispatch.
  • Fix: Use the correct URL for the fragment when reporting errors processing a web-fragment.xml file from a JAR located in an unpacked WAR.
  • Fix: Ensure that JarScanner only uses the explicit call-back to process WEB-INF/classes and only when configured to treat the contents of WEB-INF/classes as a possible exploded JAR.
  • Code: Remove the java2DDisposerProtection option from the JreMemoryLeakPreventionListener. The leak is fixed in Java 7 onwards and Tomcat 9 requires Java 8 so the option is unnecessary.
  • Code: Remove the securityPolicyProtection option from the JreMemoryLeakPreventionListener. The leak is fixed in Java 8 onwards and Tomcat 9 requires Java 8 so the option is unnecessary.
  • Code: Remove the securityLoginConfigurationProtection option from the JreMemoryLeakPreventionListener. The leak is fixed in Java 8 onwards and Tomcat 9 requires Java 8 so the option is unnecessary.

  • Update: Change the default of the sessionCookiePathUsesTrailingSlash attribute of the Context element to false since the problems caused when a Servlet is mapped to /* are more significant than the security risk of not enabling this option by default.
  • Fix: Follow-up to 59655. Improve the documentation for configuring permitted cookie names. Patch provided by Kyohei Nakamura.
  • Fix: Do not attempt to start web resources during a web application's initialisation phase since the web application is not fully configured at that point and the web resources may not be correctly configured.

  • Code: Now the WebSocket implementation is not built directly on top of the Servlet API and can use Tomcat internals, there is no need for the dedicated WebSocket Executor. It has been replaced by the use of the Connector/Endpoint provided Executor.
  • Fix: Improve error handling around user code prior to calling InstanceManager.destroy() to ensure that the method is executed.
  • Web Applications:
  • Fix: Do not log an additional case of IOExceptions in the error handler for the Drawboard WebSocket example when the root cause is the client disconnecting since the logs add no value.

  • Coyote:
  • Fix: When running on Java 7, exclude DHE ciphers from the default cipher list for JSSE connectors since they use weak 768 bit DH keys and cannot be configured to use more secure keys. (markt)
  • Add: Add a new environment variable JSSE_OPTS that is intended to be used to pass JVM wide configuration to the JSSE implementation. The default value is -Djdk.tls.ephemeralDHKeySize=2048 which protects against weak Diffie-Hellman keys with Java 8. (markt)

(markt)
  • Fix: 58357: For reasons not currently understood when the APR/native connector is used with OpenSSL reads can return an error code when there is no apparent error.

The EL specification applies when parsing the expression delimited by ${ and }. Parsing of the delimiting ${ and } is the responsibility of the JSP specification. (markt)
  • Fix: 58296: Fix a memory leak in the JSP unloading feature that meant that using a value other than -1 for maxLoadedJsps triggered a memory leak once the limit was reached. (markt)

  • Fix: In the AJP and HTTP NIO connectors, ensure that the socket timeout is correctly set before adding the socket back to the poller for read. (markt)
  • Fix: 58157: Ensure that the handling of async timeouts does not result in an unnecessary dispatch to a container thread that could result in the current socket being added to the Poller multiple times with multiple attempts to process the same event for the same socket. (markt)
  • Fix: Correct a coupe of edge cases in RequestUtil.normalize(). (markt)
  • Jasper:
  • Fix: 58110: Like scriptlet sections, declaration sections of JSP pages have a one-to-one mapping of lines to the generated .java file. Use this information to provide more accurate error messages if a compilation error occurs in a declaration section. (markt)

  • Fix: Add the WebSocket API classes to the list of classes that the web application class loader will always delegate to its parent for loading first.
  • Fix: 58015: Ensure that whenever the web application class loader checks to see if it should delegate first, it also checks the result of the filter() method which may indicate that it should always delegate first for the current class/resource regardless of the value of the delegate configuration option.

New in Apache Tomcat 8.0.22 (May 8, 2015)

  • Catalina
  • Fix: 57736: Change the format of the Tomcat specific URLs for resources inside JARs that are in turn packed in a WAR. The ^/ sequence has been replaced by */ so that the resulting URLs are compliant with RFC 2396 and do not trigger exceptions when converted to URIs. The old format will continue to be accepted. (markt)
  • Fix: 57752: Exclude non-cached resources from the Cache statistics for resource lookups. Patch provided by Adam Mlodzinski. (markt)
  • Add: Allow logging of the remote port in the access log using the format pattern %{remote}p. (rjung)
  • Fix: 57556: Refine the previous fix fo rthis issue so that the real path returned only has a trialing separator if the requested path ended with /. (markt)
  • Fix: 57765: When checking last modified times as part of the automatic deployment process, account for the fact that File.lastModified() has a resolution of one second to ensure that if a file has been modified within the last second, the latest version of the file is always used. Note that a side-effect of this change is that files with modification times in the future are treated as if they are unmodified. (markt)
  • Fix: Align redeploy resource modification checking with reload modification checking so that now, in both cases, a change in modification time rather than an increase in modification time is used to determine if the resource has changed. (markt)
  • Fix: Cleanup o.a.tomcat.util.digester.Digester from debug messages that do not give any valuable information. Patch provided by Polina Genova. (violetagg)
  • Fix: 57772: When reloading a web application and a directory representing an expanded WAR needs to be deleted, delete the directory after the web application has been stopped rather than before to avoid potential ClassNotFoundExceptions. (markt)

  • Fix: 57841: Improve error logging during web application start.
  • Fix: 57856: Ensure that any scheme/port changes implemented by the RemoteIpFilter also affect HttpServletResponse.sendRedirect().
  • Fix: 57863: Fix the RewriteMap support in RewriteValve that did not use the correct key value to look up entries.
  • Coyote:
  • Fix: 57779: When an I/O error occurs on a non-container thread only dispatch to a container thread to handle the error if using Servlet 3+ asynchronous processing. This avoids potential deadlocks if an application is performing I/O on a non-container thread without using the Servlet 3+ asynchronous API.
  • Code: Remove the experimental support for SPDY. No current user agent supports the version of SPDY that the experiment targetted. Note: HTTP/2 support is under development for Tomcat 9 and may be back-ported to Tomcat 8 once complete.
  • Fix: Possible incomplete writes with SSL NIO2.
  • Fix: Incorrect reads with SSL NIO2 caused by a bad strategy for handling IO differences between NIO and NIO2 that don't seem to be justified.
  • Fix: After some errors, the pending flags could remain set when using SSL NIO2.
  • Fix: 57833: When using JKS based keystores for NIO or NIO2, ensure that the key alias is always converted to lower caes since that is what JKS key stores expect. Based on a patch by Santosh Giri Govind M.
  • Fix: 57837: Add text/css to the default list of compressable MIME types.
  • Jasper:
  • Fix: 57845: Ensure that, if the same JSP is accessed directly and via a declaration in web.xml, updates to the JSP are visible (subject to the normal rules on re-compilation) regardless of how the JSP is accessed.
  • Fix: 57855: Explicitly handle the case where a MethodExpression is invoked with null or the wrong number of parameters. Rather than failing with an ArrayIndexOutOfBoundsException or a NullPointerException throw an IllegalArgumentException with a useful error message.
  • Cluster:
  • Fix: Avoid unnecessary call of DeltaRequest.addSessionListener() in non-primary nodes.
  • Add: Add new attribute that send all actions for session across Tomcat cluster nodes.

  • Fix: 57776: Revert the 8.0.21 fix for the permessage-deflate implementation and incorrect op-codes since the fix was unnecessary (the bug only affected trunk) and the fix broke rather than fixed permessage-deflate if an uncompressed message was converted into more than one compressed message.
  • Fix: Fix log name typo in WsRemoteEndpointImplServer class, caused by a copy-paste.
  • Fix: 57788: Avoid NPE when looking up a class hierarchy without finding anything.

  • Fix: 57864: Update the documentation web application to make it clearer that hex values are not valid for cluster send options. Based on a patch by Kyohei Nakamura.
  • Tribes:
  • Fix: Fix a concurrency issue when a backup message that has all session data and a backup message that has diff data are processing at the same time. This fix ensures that MapOwner is set to ReplicatedMapEntry.

New in Apache Tomcat 8.0.21 (Mar 28, 2015)

  • Catalina:
  • Add: 49785: Enable StartTLS connections for JNDIRealm.
  • Fix: When docBase refers internal war and unpackWARs is set to false, avoid registration of the invalid redeploy resource that has been added ".war" extension in duplicate.
  • Fix: If WAR exists, it is not necessary to trigger a reload when adding a Directory.
  • Fix: 55988: Add support for Java 8 JSSE server-preferred TLS cipher suite ordering. This feature requires Java 8.
  • Fix: 56608: When deploying an external WAR, add watched resources in the expanded directory based on whether the expanded directory is expected to exist rather than if it does exist.
  • Fix: When triggering a reload due to a modified watched resource, ensure that multiple changed watched resources only trigger one reload rather than a series of reloads.
  • Fix: 57601: Ensure that HEAD requests return the correct content length (i.e. the same as for a GET) when the requested resource includes a resource served by the Default servlet.
  • Fix: 57602: Ensure that HEAD requests return the correct content length (i.e. the same as for a GET) when the requested resource includes a resource served by a servlet that extends HttpServlet.

  • Fix: 57637: Do not create unnecessary sessions when using PersistentValve.
  • Fix: 57645: Correct a regression in the fix for 57190 that incorrectly required the path passed to ServletContext.getContext(String) to be an exact match to a path to an existing context.
  • Fix: Make sure that unpackWAR attribute of Context is handled correctly in HostConfig.
  • Fix: When deploying a WAR file that contains a context.xml file and unpackWARs is false ignore any context.xml file that may exist in an expanded directory associated with the WAR.
  • Fix: 57675: Correctly quote strings when using the extended access log.
  • Add: Enable Tomcat to detect when a WAR file has been changed while Tomcat is not running. Tomcat does this by adding a META-INF/war-tracking file to the expanded directory and setting the last modified time of this file to the last modified time of the WAR. If Tomcat detects a modified WAR via this mechanism the web application will be redeployed (i.e. the expanded directory will be removed and the modified WAR expanded in its place).
  • Fix: 57704: Fix potential NPEs during web application start/stop when org.apache.tomcat.InstanceManager is not initialized.
  • Add: Use the simplified digest output for digest.bat|sh when generating digests with no salt and a single iteration to make it easier to use with DIGEST authentication.

  • Code: Refactor Authenticator implementations to reduce code duplication.
  • Fix: 57724: Handle the case in the CORS filter where a user agent includes an origin header for a non-CORS request.
  • Fix: When searching for SCIs o.a.catalina.Context.getParentClassLoader will be used instead of java.lang.ClassLoader.getParent. Thus one can provide the correct parent class loader when running embedded Tomcat in other environments such as OSGi.
  • Fix: 57743: Fix a locked file / resource leak issue when a JAR is accessed just before or during web application undeploy.
  • Coyote:
  • Add: 57540: Make TLS/SSL protocol available in a new request attribute (org.apache.tomcat.util.net.secure_protocol_version). (Note that AJP connectors will require mod_jk 1.2.41 or later, or an as-yet-unknown version of mod_proxy_ajp, or configure the proxy to send the AJP_SSL_PROTOCOL request attribute to Tomcat.)
  • Fix: Fix a cipher ordering issue when using the OpenSSL syntax for JSSE cipher configuration to ensure that ephemeral ECDH with AES is preferred to ephemeral ECDH with anything else.
  • Fix: 57570: Make the processing of trailer headers with chunked input optional and disabled by default.
  • Fix: 57592: Correctly handle the case where an AsyncContext is used for non-blocking I/O and is completed during a write operation.
  • Fix: 57638: Avoid an IllegalArgumentException when an AJP request body chunk larger than the socket read buffer is being read. This typically requires a larger than default AJP packetSize.
  • Fix: 57674: Avoid a BufferOverflowException when an AJP response body chunk larger than the socket write buffer is being written. This typically requires a larger than default AJP packetSize.
  • Update: Align the OpenSSL syntax cipher configuration with the OpenSSL 1.0.2 branch.
  • Fix: Numerous fixes to the APR/native connector to improve robustness.
  • Fix: Stop caching and re-using SocketWrapper instances. With the introduction of upgrade and non-blocking I/O, I/O can occur on non-container threads. This makes it nearly impossible to track whether a SocketWrapper is still being references or not. making re-use a risky proposition.
  • Code: Refactor Connector authentication (only used by AJP) into a separate method.
  • Add: 57708: Implement a new feature for AJP connectors - Tomcat Authorization. If the new tomcatAuthorization attribute is set to true (it is disabled by default) Tomcat will take an authenticated user name from the AJP protocol and use the appropriate Realm for the request to authorize (i.e. add roles) to that user.
  • Fix: Fix an issue that meant that any pipe-lined data read by Tomcat before an asynchronous request completed was lost during the completion of the asynchronous request. This mean that the pipe-lined request(s) would be lost and/or corrupted.
  • Update: Update the minimum recommended version of the Tomcat Native library (if used) to 1.1.33.
  • Jasper:
  • Fix: 57135: Package imports via javax.el.ImportHandler should only import public, concrete classes.
  • Fix: 57583: Cache 'Not Found' results in javax.el.ImportHandler.resolveClass() to save repeated attempts to load classes that are known not to exist to improve performance.
  • Fix: 57626: Correct a regression introduced in the 8.0.16 fix for ensuring Jars were closed after use, that broke recompilation of modified JSPs that depended on a tag file packaged in a Jar.
  • Fix: 57627: Correctly determine last modified times for dependencies when a tag file packaged in a JAR depends on a tag file packaged in a second JAR.
  • Fix: 57647: Ensure INFO message is logged when scanning jars for TLDs if the scan does not find a TLD in any jar. Previously a message would only be logged if a TLD was not found in all scanned jars.
  • Update: 57662: Update all references to the ECJ compiler to version 4.4.2.
  • Cluster:
  • Fix: Remove unnecessary method that always returns true. The domain filtering works on DomainFilterInterceptor.

  • Add: 57676: List conflicting WebSocket endpoint classes when there is a path conflict.
  • Web applications:
  • Fix: 56058: Add links to the AccessLogValve documentation for configuring reverse proxies and/or Tomcat to ensure that the desired information is used entered in the access log when Tomcat is running behind a reverse proxy.

  • Fix: Remove incorrect note from context configuration page in the documentation web application that stated WAR files located outside the appBase were never unpacked.
  • Fix: 57683: Ensure that if a client aborts their connection to the stock ticker example (the only way a client can disconnect), the example continues to work for existing and new clients.
  • Fix: Make it clear that when using digested passwords with DIGEST authentication that no salt and only a single iteration must be used when generating the digest.
  • Update: Update examples to use Apache Standard Taglib 1.2.5.
  • Extras:
  • Fix: 57377: Remove the restriction that prevented the use of SSL when specifying a bind address with the JMXRemoteLifecycleListener. Also enable SSL to be configured for the registry as well as the server.

  • Add: Add support for the permessage-deflate extension. This is currently limited to decompressing incoming messages on the server side. It is expected that support will be extended to outgoing messages and to the client side shortly. (markt)
  • Web applications:
  • Fix: Attempt to obfuscate session cookie values associated with other web applications when viewing HTTP request headers with the Cookies example from the examples web application. This reduces the opportunity to use this example for malicious purposes should the advice to remove the examples web application from security sensitive systems be ignored. (markt)

  • Fix: 55975: Apply consistent escaping for double quote and backslash characters when escaping cookie values. (markt)
  • Code: 56387: Improve the code that handles an attempt to load a class after a web application has been stopped. Use common code to handle this case regardless of the access path and don't throw an exception purely to log a stack trace. (markt)
  • Code: 56399: Improve implementation of CoyoteAdapter.checkRecycled() to do not use an exception for flow control. (kkolinko)

  • Update: 56546: Reduce logging level for stack traces of stuck web application threads printed by WebappClassLoader.clearReferencesThreads() from error to info. (kkolinko)
  • Code: Refactor and simplify common code in object factories in org.apache.catalina.naming package, found thanks to Simian (Similarity Analyser) tool. Improve handling of Throwable. (markt/kkolinko)
  • Fix: Relax cookie naming restrictions. Cookie attribute names used in the Set-Cookie header may be used unambiguously as cookie names. The restriction that prevented such usage has been removed. (jboynes/markt)
  • Fix: Further relax cookie naming restrictions. Version 0 (a.k.a Netscape format) cookies may now use names that start with the $ character. (jboynes/markt)
  • Fix: Restrict cookie naming so that the = character is no longer permitted in a version 0 (a.k.a. Netscape format) cookie name. While Tomcat allowed this, browsers always truncated the name at the = character leading to a mis-match between the cookie the server set and the cookie returned by the browser. (jboynes/markt)
  • Add: Add a simple ServiceLoader based discovery mechanism to the JULI LogFactory to make it easier to use JULI and Tomcat components that depend on JULI (such as Jasper) independently from Tomcat. Patch provided by Greg Wilkins. (markt)

  • Fix: If request contains an unrecognized Expect header, respond with error 417 (Expectation Failed), according to RFC2616 chapter 14.20. (markt)
  • Fix: When an error occurs after the response has been committed close the connection immediately rather than attempting to finish the response to make it easier for the client to differentiate between a complete response and one that failed part way though. (markt)
  • Code: Remove the beta tag from the NIO2 connectors. (remm)
  • Fix: 56620: Avoid bogus access log entries when pausing the NIO HTTP connector and ensure that access log entries generated by error conditions use the correct request start time. (markt)

  • Fix: 56568: Allow any HTTP method when a JSP is being used as an error page. (markt)
  • Update: 56581: If an error on a JSP page occurs when response has already been committed, do not clear the buffer of JspWriter, but flush it. It will make more clear where the error occurred. (kkolinko)
  • Fix: 56612: Correctly parse two consecutive escaped single quotes when used in UEL expression in a JSP. (markt)
  • Update: Move code that parses EL expressions within JSP template text from Parser to JspReader class for better performance. (kkolinko)
  • Fix: 56636: Correctly identify the required method when specified via ELProcessor.defineFunction(String,String,String,String) when using Expression Language. (markt)
  • Fix: 56638: When using ELProcessor.defineFunction(String,String,String,String) and no function name is specified, use the method name as the function name as required by the specification. (markt)
  • WebSocket:
  • Code: 56446: Clearer handling of exceptions when calling a method on a POJO based WebSocket endpoint. Based on a suggestion by Eugene Chung. (markt)
  • Fix: When a WebSocket client attempts to write to a closed connection, handle the resulting IllegalStateException in a manner consistent with the handling of an IOException. (markt)
  • Fix: Add more varied endpoints for echo testing. (remm)
  • Fix: 56577: Improve the executor configuration used for the callbacks associated with asynchronous writes. (markt)
  • Web applications:
  • Fix: Set the path for cookies created by the examples web application so they only returned to the examples application. This reduces the opportunity for using such cookies for malicious purposes should the advice to remove the examples web application from security sensitive systems be ignored. (markt/kkolinko)
  • Fix: Attempt to obfuscate session cookie values associated with other web applications when viewing HTTP request headers with the Request Header example from the examples web application. This reduces the opportunity to use this example for malicious purposes should the advice to remove the examples web application from security sensitive systems be ignored. (markt)

New in Apache Tomcat 7.0.54 (May 24, 2014)

  • Catalina:
  • Fix custom UTF-8 decoder so that a byte of value 0xC1 is always rejected immediately as it is never valid in a UTF-8 byte sequence. Update UTF-8 decoder tests to account for UTF-8 decoding improvements in Java 8. The custom UTF-8 decoder is still required due to bugs in the UTF-8 decoder provided by Java. Java 8's decoder is better than Java 7's but it is still buggy. (markt)
  • 56027: Add more options for managing FIPS mode in the AprLifecycleListener. (schultz/kkolinko)
  • 56321: When a WAR is modified, undeploy the web application before deleting any expanded directory as the undeploy process may refer to classes that need to be loaded from the expanded directory. If the expanded directory is deleted first, any attempt to load a new class during undeploy will fail. (markt)
  • 56339: Avoid an infinite loop if an application calls session.invalidate() from the session destroyed event for that session. (markt)
  • 56365: Simplify file name pattern matching code in StandardJarScanner. Ignore leading and trailing whitespace and empty strings when configuring patterns. Improve documentation. (kkolinko)
  • 56369: Ensure that removing an MBean notification listener reverts all the operations performed when adding an MBean notification listener. (markt)

  • Correct regression introduced in r797162 that broke authentication of users when using the JAASMemoryLoginModule. (markt)
  • 56501: HttpServletRequest.getContextPath() should return the undecoded context path used by the user agent. (markt)
  • 56523: When using SPNEGO authentication, log the exceptions associated with failed user logins at debug level rather than error level. (markt)
  • 56536: Ensure that HttpSessionBindingListener.valueUnbound() uses the correct class loader when the SingleSignOn valve is used. (markt)
  • Coyote:
  • 56399: Assert that both Coyote and Catalina request objects have been properly recycled. (kkolinko)
  • 56416: Correct documentation for default value of socket linger for the AJP and HTTP connectors. (markt)
  • Jasper:
  • 56334: Fix a regression in the handling of back-slash escaping introduced by the fix for 55735. (markt/kkolinko)
  • 56425: Improve method matching for EL expressions. When looking for matching methods, an exact match between parameter types is preferred followed by an assignable match followed by a coercible match. (markt)
  • Correct the handling of back-slash escaping in the EL parser and no longer require that \$ or \# must be followed by { in order for the back-slash escaping to take effect. (markt)
  • 56529: Avoid NoSuchElementException while handling attributes with empty string value in custom tags. Patch provided by Hariprasad Manchi. (violetagg)
  • Cluster:

  • Add support for cross context session replication to org.apache.catalina.ha.session.BackupManager. (kfujino)
  • Remove the unnecessary cross context check. It does not matter whether the context that is referenced by other context is set to crossContext=true. The context that refers to the different context must be set to crossContext=true. (kfujino)
  • Move to org.apache.catalina.ha.session.ClusterManagerBase common logics of org.apache.catalina.ha.session.BackupManager and org.apache.catalina.ha.session.DeltaManager. (kfujino)
  • Simplify the code of o.a.c.ha.tcp.SimpleTcpCluster. In order to add or remove cluster valve to Container, use pipeline instead of IntrospectionUtils. (kfujino)
  • There is no need to set cluster instance when SimpleTcpCluster.unregisterClusterValve is called. Set null than cluster instance for cleanup. (kfujino)
  • Backport refactoring of AbstractReplicatedMap to implement Map rather than extend ConcurrentHashMap to enable Tomcat 7 to be built with Java 8. (markt)

  • Increase the default maximum size of the executor used by the WebSocket implementation for call backs associated with asynchronous writes from 10 to 200. (markt)
  • Add a warning if the thread group created for WebSocket asynchronous write call backs can not be destroyed when the web application is stopped. (markt)
  • Ensure that threads created to support WebSocket clients are stopped when no longer required. This will happen automatically for WebSocket client connections initiated by web applications but stand alone clients must call WsWebSocketContainer.destroy(). (markt)
  • 56449: When creating a new session, add the message handlers to the session before calling Endpoint.onOpen() so the message handlers are in place should the onOpen() method trigger the sending of any messages. (markt)
  • 56458: Report WebSocket sessions that are created over secure connections as secure rather than as not secure. (markt)

  • 56219: Improve merging process for web.xml files to take account of the elements and attributes supported by the Servlet version of the merged file. (markt)
  • 56190: The response should be closed (i.e. no further output is permitted) when a call to AsyncContext.complete() takes effect. (markt)
  • 56236: Enable Tomcat to work with alternative Servlet and JSP API JARs that package the XML schemas in such as way as to require a dependency on the JSP API before enabling validation for web.xml. Tomcat has no such dependency. (markt)
  • 56246: Fix NullPointerException in MemoryRealm when authenticating an unknown user. (markt)
  • 56248: Allow the deployer to update an existing WAR file without undeploying the existing application if the update flag is set. This allows any existing custom context.xml for the application to be retained. To update an application and remove any existing context.xml simply undeploy the old version of the application before deploying the new version. (markt)
  • Redefine the globalXsltFile initialisation parameter of the DefaultServlet as relative to CATALINA_BASE/conf or CATALINA_HOME/conf. Prevent user supplied XSLTs used by the DefaultServlet from defining external entities. (markt)
  • Add a work around for validating XML documents (often TLDs) that use just the file name to refer to refer to the JavaEE schema on which they are based. (markt)
  • 56293: Cache resources loaded by the class loader from /META-INF/services/ for better performance for repeated look ups. (markt)
  • Coyote:
  • 53119: Make sure the NIO AJP output buffer is cleared on any error to prevent any possible overflow if it is written to again before the connection is closed. This extends the original fix for the APR/native output buffer to the NIO connector. (kkolinko)
  • 56172: Avoid possible request corruption when using the AJP NIO connector and a request is sent using more than one AJP message. Patch provided by Amund Elstad. (markt)
  • 56213: Reduce garbage collection when the NIO connector is under heavy load. (markt)
  • Improve processing of chuck size from chunked headers. Avoid overflow and use a bit shift instead of a multiplication as it is marginally faster. (markt/kkolinko)
  • Fix possible overflow when parsing long values from a byte array. (markt)
  • Jasper:
  • 54475: Add Java 8 support to SMAP generation for JSPs. Patch by Robbie Gibson. (markt)
  • 55483: Improve handing of overloaded methods and constructors in expression language implementation. (markt)
  • 56208: Restore the validateXml option to Jasper that was previously renamed validateTld. Both options are now supported. validateXml controls the validation of web.xml files when Jasper parses them and validateTld controls the validation of *.tld files when Jasper parses them. (markt)
  • 56223: Throw an IllegalStateException if a call is made to ServletContext.setInitParameter() after the ServletContext has been initialized. (markt)
  • 56265: Do not escape values of dynamic tag attributes containing EL expressions. (kkolinko)

  • Add support for LAST_ACCESS_AT_START system property to Manager web application. (kfujino)
  • Add definition of org.apache.catalina.ant.FindLeaksTask. (kfujino)
  • 56273: If the Manager web application does not perform an operation because the web application is already being serviced, report an error rather than reporting success. (markt)
  • 56304: Add a note to the documentation about not using WebSocket with BIO HTTP in production. (markt)
  • Other:
  • 56143: Improve service.bat so that it can be launched from a non-UAC console. This includes using a single call to tomcat7.exe to install the Windows service rather than three calls, and using command line arguments instead of environment variables to pass the settings. (markt/kkolinko)
  • Fix regression in 7.0.52: when using service.bat install to install the service the values for --StdOutput, --StdError options were passed as blank instead of "auto". (kkolinko)
  • Align options between service.bat and exe Windows installer. For service.bat the changes are in --Classpath, --DisplayName, --StartPath, --StopPath. For exe installer the changes are in --JvmMs, --JvmMx options, which are now 128 Mb and 256 Mb respectively instead of being empty. Explicitly specify --LogPath path when uninstalling Windows service, avoiding default value for that option. (kkolinko)
  • Simplify Windows *.bat files: remove %OS% checks, as java 6 does not run on ancient non-NT operating systems. (kkolinko)
  • 56137: Explicitly use the BIO connector in the SSL example in server.xml so it doesn't break if APR is enabled. (markt)
  • 56139: Avoid a web application class loader leak in some unit tests when running on Windows. (markt)
  • Correct build script to avoid building JARs with empty packages. (markt)
  • Allow to limit JUnit test run to a number of selected test case methods. (kkolinko)

  • 56304: Add a note to the documentation about not using WebSocket with BIO HTTP in production. (markt)

New in Apache Tomcat 7.0.52 (Feb 20, 2014)

  • Catalina:
  • Generate a valid root element for the effective web.xml for a web application for all supported versions of web.xml. (markt)
  • Coyote:
  • Pull up SocketWrapper to AbstractProcessor. (markt)
  • In some circumstances asynchronous requests could time out too soon. (markt)

New in Apache Tomcat 8.0.3 Beta (Feb 13, 2014)

  • Fix CVE-2014-0050, a DoS vulnerability related to multi-part processing.
  • Fix WebDAV support broken by the resources refactoring.
  • Enable non-blocking reads to take place on non-container threads.

New in Apache Tomcat 8.0.1 Beta (Feb 3, 2014)

  • Catalina:
  • Change default value of xmlBlockExternal attribute of Context. It is true now.
  • Coyote:
  • Correct regression in the fix for 55996 that meant that asynchronous requests might timeout too early.
  • Jasper:
  • Change default value of the blockExternal attribute of JspC task. The default value is true. Add support for -no-blockExternal switch when JspC is run as a standalone application.
  • WebSocket:
  • Do not return an empty string for the Sec-WebSocket-Protocol HTTP header when no sub-protocol has been requested or no sub-protocol could be agreed as RFC6455 requires that no Sec-WebSocket-Protocol header is returned in this case.

New in Apache Tomcat 7.0.50 (Jan 13, 2014)

  • Catalina:
  • Handle the case where a context.xml file is added to a web application deployed from a directory. Previously the file was ignored until Tomcat was restarted. Now (assuming automatic deployment is enabled) it will trigger a redeploy of the web application. (markt)
  • Fix string comparison in HostConfig.setContextClass(). (kkolinko)
  • code Streamline handling of WebSocket messages whe no handler is configured for the message currently being received. (markt)
  • Handle the case where a WebSocket annotation configures a message size limit larger than the default permitted by Tomcat. (markt)
  • This is a partial fix that bypasses the relatively expensive check for a WebSocket upgrade request if no WebSocket endpoints have been registered. (markt)
  • Prevent a NPE when web.xml references a taglib file that does not exist. Provide better error message. (violetagg)
  • Coyote:
  • When using the BIO connector with an internal executor, do not display a warning that the executor has not shutdown as the default configuration for BIO connectors is not to wait. This is because threads in keep-alive connections cannot be interrupted and therefore the warning was nearly always displayed. (markt)
  • Jasper:
  • JspC uses servlet context initialization parameters to pass configuration so ensure that the servlet context used supports initialization parameters. (markt)
  • Cluster:
  • In AbstractReplicatedMap#finalize, remove rpcChannel from channel Listener of group channel before sending MapMessage.MSG_STOP message. This prevents that the node that sent the MapMessage.MSG_STOP by normal shutdown is added to member map again by ping at heartbeat thread in the node that received the MapMessage.MSG_STOP. (kfujino)
  • Add time stamp to GET_ALL_SESSIONS message. (kfujino)
  • Web applications:
  • Fix the sample configuration of StaticMembershipInterceptor in order to prevent warning log. uniqueId must be 16 bytes. (kfujino)
  • Extras:
  • Update dependencies that are used to build tomcat-juli extras component. Apache Avalon Framework is updated to version 4.1.5, Apache Log4J to version 1.2.17. (rjung)

New in Apache Tomcat 8.0.0 RC 10 (Dec 28, 2013)

  • Catalina:
  • Implement JSR 340 - Servlet 3.1. The JSR 340 implementation includes contributions from Nick Williams and Jeremy Boynes. (markt)
  • Implement JSR 245 MR2 - JSP 2.3. (markt)
  • Implement JSR 341 - Unified Expression Language 3.0. (markt)
  • Implement JSR 356 - WebSockets. The JSR 356 implementation includes contributions from Nick Williams, Rossen Stoyanchev and Niki Dokovski. (markt)
  • 46727: Refactor default servlet to make it easier to sub-class to implement finer grained control of the file encoding. Based on a patch by Fred Toth. (markt)
  • 45995: Align Tomcat with Apache httpd and perform MIME type mapping based on file extension in a case insensitive manner. (markt)
  • Remove duplicate code that converted a Host's appBase attribute to a canonical file. (markt)
  • 51408: Replace calls to Charset.defaultCharset() with an explicit reference to the ISO-8859-1 Charset. (markt)
  • Refactor initialization code to use a single, consistent approach to determining the Catalina home (binary) and base (instance) directories. The search order for home is catalina.home system property, parent of current directory if boootstrap.jar is present and finally current working directory. The search order for Catalina base is catalina.base system property falling back to the value for Catalina home. (markt)
  • 52092: JULI now uses the OneLineFormatter and AsyncFileHandler by default. (markt)
  • 52558: Refactor CometConnectionManagerValve so that it does not prevent the session from being serialized in when running in a cluster. (markt)
  • 52767: Remove reference to MySQL specific autoReconnect property in JDBCAccessLogValve. (markt)
  • Make the Mapper type-safe. Hosts, Contexts and Wrappers are no longer handled as plain objects, instead they keep their type. Code using the Mapper doesn't need to cast objects returned by the mapper. (rjung)
  • Move Manager, Loader and Resources from Container to Context since Context is the only place they are used. The documentation already states (and has done for some time) that Context is the only valid location for these nested components. (markt)
  • Move the Mapper from the Connector to the Service since the Mapper is identical for all Connectors of a given Service and it is common for there to be multiple Connectors for a Service (http, https and ajp). This means there is now only ever one Mapper per Service rather than possibly multiple identically configured Mapper objects. (markt)
  • Remove the per Context Mapper objects and use the Mapper from the Service. This removes the need to maintain two copies of the mappings for Servlets and Filters. (markt)
  • Implement a new Resources implementation that merges Aliases, VirtualLoader, VirtualDirContext, JAR resources and external repositories into a single framework rather than a separate one for each feature. (markt)
  • URL rewrite valve, similar in functionality to mod_rewrite. (remm)
  • Port storeconfig functionality, which can persist to server.xml and context.xml runtime container configuration changes. (remm)
  • 54095: Add support to the Default Servlet for serving gzipped versions of static resources directly from disk as an alternative to Tomcat compressing them on each request. Patch by Philippe Marschall. (markt)
  • 54708: Change the name of the working directory for the ROOT application (located under $CATALINA_BASE/work by default) from _ to ROOT. (markt)
  • Change default configuration so that a change to the global web.xml file will trigger a reload of all web applications. (markt)
  • 55101: Make BASIC authentication more tolerant of whitespace. Patch provided by Brian Burch. (markt)
  • 55166: Move JSP descriptor and tag library descriptor schemas to servlet-api.jar to enable relative references between the schemas to be correctly resolved. (markt)
  • Refactor the descriptor parsing code into a separate module that can be used by both Catalina and Jasper. Includes patches provided by Jeremy Boynes. (violetagg/markt)
  • 55246: Move TLD scanning to a ServletContainerInitializer provided by Jasper. Includes removal of TldConfig lifecycle listener and associated Context properties. (jboynes)
  • 55317: Facilitate weaving by allowing ClassFileTransformer to be added to WebppClassLoader. Patch by Nick Williams. (markt)
  • 55620: Enable Tomcat to start when either $CATALINA_HOME and/or $CATALINA_BASE contains a comma character. Prevent Tomcat from starting when $CATALINA_HOME and/or $CATALINA_BASE contains a semi-colon on Windows. Prevent Tomcat from starting when $CATALINA_HOME and/or $CATALINA_BASE contains a colon on Linux/FreeBSD/etc. (markt)
  • Initialize the JSP runtime in Jasper's initializer to avoid need for a Jasper-specific lifecycle listener. JasperListener has been removed. (jboynes)
  • Chnage ordering of elements of JMX objects names so components are grouped more logically in JConsole. Generally, components are now grouped by Host and then by Context. (markt)
  • Coyote:
  • Experimental support for SPDY. Includes contributions from Sheldon Shao. (costin)
  • The default connector is now the Java NIO connector even when specifying HTTP/1.1 as protocol (fhanik)
  • Update default value of pollerThreadCount for the NIO connector. The new default value will never go above 2 regardless of available processors. (fhanik)
  • 54010: Remove some unnecessary code (duplicate calls to configure the scheme as https for AJP requests originally received over HTTPS). (markt)
  • Refactor char encoding/decoding using NIO APIs. (remm)
  • Change the default URIEncoding for all connectors from ISO-8859-1 to UTF-8. (markt)
  • Jasper:
  • Simplify API of ErrorDispatcher class by using varargs. (kkolinko)
  • Update Jasper to use the new common web.xml parsing code. Includes patches by Jeremy Boynes. (markt/violetagg)
  • Create test cases for JspC. Patch by Jeremy Boynes. (markt)
  • 55246: TLD scanning is now performed by JasperInitializer (a ServletContainerInitializer) removing the need for support within the Servlet container itself. The scan is now performed only once rather than in two passes reducing startup time. (jboynes)
  • 55251: Do not allow JspC task to fail silently if the web.xml or web.xml fragment can not be generated. (markt)
  • Cluster:
  • Remove unused JvmRouteSessionIDBinderListener and SessionIDMessage. (kfujino)
  • Modify method signature in ReplicationValve. Cluster instance is not necessary to argument of method. (kfujino)
  • Remove unused expireSessionsOnShutdown attribute in org.apache.catalina.ha.session.BackupManager. (kfujino)
  • Web applications:
  • Extend the diagnostic information provided by the Manager web application to include details of the configured SSL ciphers suites for each connector. (markt)
  • 48550: Update examples web application to use UTF-8. (markt)
  • 55383: Improve the design and correct the HTML markup of the documentation web application. Patches provided by Konstantin Preißer. (markt)
  • Tribes:
  • Refactor AbstractReplicatedMap to use generics. A key side-effect of this is that the class now implements Map rather than extends ConcurrentMap. (markt)
  • Other:
  • Remove unused, deprecated code. (markt)
  • Remove static info String and associated getInfo() method where present. (markt)
  • (r1353242, r1353410): Remove Ant tasks jasper2 and jkstatus. The correct names are jasper and jkupdate. (kkolinko)
  • 53529: Clean-up the handling of InterruptedException throughout the code base. (markt)
  • 54899: Provide an initial implementation of NetBeans support. Patch provided by Brian Burch. (markt)
  • 55166: Move the JSP descriptor and tag library descriptor schema defintion files from jsp-api.jar to servlet-api.jar so relative includes between the J2EE, Servlet and JSP schemas are correctly resolved. (markt)
  • 55372: When starting Tomcat with the jpda option to enable remote debugging, by default only listen on localhost for connections from a debugger. Prior to this change, Tomcat listened on all known addresses. (markt)

New in Apache Tomcat 7.0.47 (Oct 26, 2013)

New in Apache Tomcat 7.0.39 (Mar 27, 2013)

  • Web application reloading and static fields in shared libraries:
  • Some shared libraries (many are part of the JDK) keep references to objects instantiated by the web application. To avoid class loading related problems (ClassCastExceptions, messages indicating that the classloader is stopped, etc.), the shared libraries state should be reinitialized.
  • Something which might help is to avoid putting classes which would be referenced by a shared static field in the web application classloader, and putting them in the shared classloader instead (JARs should be put in the "lib" folder, and classes should be put in the "classes" folder).
  • Enabling SSI and CGI Support:
  • Because of the security risks associated with CGI and SSI available to web applications, these features are disabled by default.
  • Security manager URLs:
  • In order to grant security permissions to JARs located inside the web application repository, use URLs of of the following format in your policy file: file:${catalina.base}/webapps/examples/WEB-INF/lib/driver.jar
  • Symlinking static resources:
  • By default, Unix symlinks will not work when used in a web application to link resources located outside the web application root directory. This behavior is optional, and the "allowLinking" flag may be used to disable the check.

  • Include the exception in the log message if the parsing of the context.xml file fails.
  • 54497: Make memory leak detection code more robust so a failure in the leak detection code does not prevent the Context from stopping unless the error is fatal to the JVM.
  • 54507: Do not start the background thread that is used to expiring sessions (amongst other things) until the web application is fully started. Stop the background thread as soon as the web application is stopped.
  • Coyote:
  • 54324: Allow APR connector to disable TLS compression if OpenSSL supports it.
  • 54406: Fix NIO HTTPS connector to prune specified ciphers and sslEnableProtocols options to those supported by the SSL implementation, sharing logic with the BIO connector. Modified ciphers and sslEnabledProtocols option pruning to not silently revert to JVM defaults when none of the options specified are supported - new behaviour is to warn and explicitly enable no options.
  • Align NIO HTTP connector with other HTTP connectors and include leading blank lines when determining the size of the HTTP headers
  • Jasper:
  • 53869: Performance improvement for pages with lots of heavily nested tags. Retain a reference to the root JSP context rather than traversing the hierarchy on every call. Based on a patch suggested by Sheldon Shao.

New in Apache Tomcat 7.0.32 (Oct 8, 2012)

  • Bundled APIs:
  • A standard installation of Tomcat 7.0 makes all of the following APIs available for use by web applications (by placing them in "lib"):
  • annotations-api.jar (Annotations package)
  • catalina.jar (Tomcat Catalina implementation)
  • catalina-ant.jar (Tomcat Catalina Ant tasks)
  • catalina-ha.jar (High availability package)
  • catalina-tribes.jar (Group communication)
  • ecj-3.7.2.jar (Eclipse JDT Java compiler)
  • el-api.jar (EL 2.2 API)
  • jasper.jar (Jasper 2 Compiler and Runtime)
  • jasper-el.jar (Jasper 2 EL implementation)
  • jsp-api.jar (JSP 2.2 API)
  • servlet-api.jar (Servlet 3.0 API)
  • tomcat-api.jar (Interfaces shared by Catalina and Jasper)
  • tomcat-coyote.jar (Tomcat connectors and utility classes)
  • tomcat-dbcp.jar (package renamed database connection pool based on Commons DBCP)
  • You can make additional APIs available to all of your web applications by putting unpacked classes into a "classes" directory (not created by default), or by placing them in JAR files in the "lib" directory.
  • To override the XML parser implementation or interfaces, use the endorsed mechanism of the JVM. The default configuration defines JARs located in "endorsed" as endorsed.
  • Web application reloading and static fields in shared libraries:
  • Some shared libraries (many are part of the JDK) keep references to objects instantiated by the web application. To avoid class loading related problems (ClassCastExceptions, messages indicating that the classloader is stopped, etc.), the shared libraries state should be reinitialized.
  • Something which might help is to avoid putting classes which would be referenced by a shared static field in the web application classloader, and putting them in the shared classloader instead (JARs should be put in the "lib" folder, and classes should be put in the "classes" folder).

New in Apache Tomcat 7.0.30 (Sep 6, 2012)

  • Dependency Changes:
  • Tomcat @VERSION_MAJOR_MINOR@ is designed to run on Java SE 6 and later.
  • In addition, Tomcat @VERSION_MAJOR_MINOR@ uses the Eclipse JDT Java compiler for compiling JSP pages. This means you no longer need to have the complete Java Development Kit (JDK) to run Tomcat, but a Java Runtime Environment (JRE) is sufficient. The Eclipse JDT Java compiler is bundled with the binary Tomcat distributions. Tomcat can also be configured to use the compiler from the JDK to compile JSPs, or any other Java compiler supported by Apache Ant.
  • API Stability:
  • The public interfaces for the following classes are fixed and will not be changed at all during the remaining lifetime of the 7.x series: - javax/**/*
  • The public interfaces for the following classes may be added to in order to resolve bugs and/or add new features. No existing interface will be removed or changed although it may be deprecated. - org/apache/catalina/* - org/apache/catalina/comet/*
  • Note: As Tomcat 7 matures, the above list will be added to. The list is not considered complete at this time.
  • The remaining classes are considered part of the Tomcat internals and may change without notice between point releases.
  • JNI Based Applications:
  • Applications that require native libraries must ensure that the libraries have been loaded prior to use. Typically, this is done with a call like: static { System.loadLibrary("path-to-library-file"); } in some class. However, the application must also ensure that the library is not loaded more than once. If the above code were placed in a class inside the web application (i.e. under /WEB-INF/classes or /WEB-INF/lib), and the application were reloaded, the loadLibrary() call would be attempted a second time.
  • To avoid this problem, place classes that load native libraries outside of the web application, and ensure that the loadLibrary() call is executed only once during the lifetime of a particular JVM.

The base Lifecycle implementation has been improved to allow failed web applications to be started once the configuration issues have been resolved. Any changes to a context.xml file (global, per host or web application specific) will now result in a redeploy of the affected web application(s) that ensures that any changes are correctly applied rather than a reload which ignores changes in context.xml files.

  • Work around a known JVM bug that is fixed in 1.7.0_01 but still present in 1.6.0_29 and was triggering intermittent unit test failures for org.apache.catalina.tribes.group. TestGroupChannelMemberArrival.testMemberArrival. The bug affects any components that use NIO although it was more likely to be observed in the clustering module than the HTTP or AJP NIO connector. (markt)
  • When Context manager does not exist, no context manager message is replied in order to avoid timeout (default 60sec) of GET_ALL_SESSIONS sync phase. (kfujino)
  • Fix setting maxInactiveInterval, sessionIdLength and processExpiresFrequency for cluster managers. Use setter when setting maxActiveSessions. (rjung)
  • Web applications:
  • 50923: Use distinct background color for code tag in Tomcat documentation, for better readability. (kkolinko)

  • 52148: Add tomcat-coyote.jar to catalina-tasks.xml as this JAR is now required by the Ant tasks. Patch provided by Volker Krebs. (markt)
  • In jdbc-pool: Improve handling of Errors that originate from methods invoked through reflection. In TrapException interceptor: rethrow Error as is, without wrapping it in a RuntimeException. (kkolinko)
  • In jdbc-pool: Unwrap InvocationTargetException if it is caught in ResultSetProxy, like we do it elsewhere. (kkolinko)
  • When building jdbc-pool from within Tomcat, use Tomcat's output directory location. This allows to move all build output away from the source tree. (kkolinko)

  • 51774: Fix incorrect cached method signature that prevented session tracking modes from being defined in web.xml when running under a security manager. (markt)
  • Add an annotation cache to the DefaultInstanceManager that improves performance for applications that make use of a lot of non-poolable objects (e.g. tag files) that need to be scanned for annotations when created. (markt)

  • Accept AJP request even if endpoint is paused, if CPING was successful. (rjung)
  • Jasper:
  • When unloading JSPs due to configuration of the maxLoadedJsps initialisation parameter, the unloading code was retaining a reference to the to the unloaded JSP preventing the associated class from being unloaded until the JSP that replaced it was itself unloaded. (markt)
  • 51852: Correct two problems in the handling of varargs methods with the BeanELResolver. The first meant the wrong method was sometimes called and the second that an ArrayIndexOutOfBoundsExceptions could be thrown. Patch (including a test case) provided by Matt Benson. (markt)
