  • Support for compiling scripts in JProfiler with Java 9 JREs
  • Support for profiling Java 10
  • Improved the startup time of the JProfiler UI
  • Removed the "Live instances" GC root in the heap walker, so it is easier to solve class loader leaks
  • Added an overview telemetry for probes like for the VM telemetries, so you can see all telemetries of a probe at once
  • Implemented quick search in the node detail dialog
  • Added an export option for including the session name in the suggested file name
  • Added configurable time scales for the call graph and the table views in the "Monitors & Locks" view section

  • Executor request tracking can now reliably track multiple usages of the same Runnable instance
  • Added request tracking support for classic EJBs on Wildfly 11
  • Graph views: Ctrl+Space (Cmd+Space on macOS) toggles selection of highlighted nodes when quick search is active
  • eclipse IDE integration: Improved source navigation to lambda methods and anonymous classes
  • The session settings for snapshots are now unmodifiable to prevent confusion
  • Added a "Run GC" trigger action
  • Bugs fixed:
  • Heap walker: The path to GC root search did not prefer shortest paths and opened unhelpful nested GC roots when multiple roots should be found
  • Method splitting: Fixed a call tree corruption that occurred if an unprofiled split method threw an exception
  • Method splitting: The hyperlink for resetting the splitting cap was not displayed in the call tree
  • When opening a snapshot and choosing the deobfuscation option in the file chooser, choosing "None" as the deobfuscator prevented opening of the snapshot
  • MBean browser: The filter text field for the MBean tree was broken
  • Unfreezing the monitor history view or the locking history graph removed all extra tool bar buttons
  • Command line comparisons: Using the "sortByTime" option could lead to a ConcurrentModificationException
  • jpanalyze did not work with a floating license server
  • Probes could prevent classloader garbage collection by holding on to instrumented classes
  • Heap walker: If selecting retained objects with the "Thread locals" inspection, weakly referenced objects could be included

  • Scripts did not resolve classes from directory class path entries that contained JAR files
  • Regression in 9.2: Monitor tool tips in thread history views were not displayed anymore
  • Applying overhead hot spots did not save the session settings, so these changes could easily get lost
  • eclipse IDE integration: The preference page did not show the JProfiler executable when no profiling session had been started yet after performing the integration from the JProfiler UI
  • Quick search in the locking history graph did not work
  • Disabling request tracking in the profiling settings did not completely disable all tracking types
  • After applying new profiling settings in a live profiling session, it was not possible to add or edit custom telemetries
  • The time in the header of the live allocation views was not updated if the view was recalculated from the "Show classes" analysis or due to a call tree root change
  • Status bar information when hovering over tool tips in graphs were hidden after a short time in live sessions
  • Heap walker: Stack traces in the node detail dialog of the incoming references view were wrapped unless the detail dialog was shown with the "Show more" hyperlink
  • macOS: Repeated use of the right arrow key did not select first child nodes in trees other than call trees
  • Class tracker: It was not possible to select the tracked class for the command line export
  • When the "Expand entire tree" option was selected in the export options dialog of the hot spots view, the export would hang
  • The default thread status for the method statistics command line export as well as for the probe call tree and probe hot spot command line comparisons was "Runnable" and not "All states" like in the GUI.
  • Fixed a rare deadlock at startup when profiling Java 1.6 VMs
  • File watcher thread and some NIO channels were shown in the runnable thread state
  • There was no auto-update for floating probe views if the probe was not selected in the main window
  • It was possible to invoke the "Add exceptional method", "Split method with a script" and the "Add method trigger" action for native and abstract methods that cannot be instrumented
  • Under some circumstances, the initial window size on macOS could be minimal, only showing the window controls
  • When saving a snapshot with jpcontroller and the specified relative path was not writable, a message with the wrong absolute path was written to the terminal
  • For generic types, the code editor suggested non-public methods and fields in code completion

  • Bugs fixed:
  • macOS: Fixed the empty menu bar that could occur with macos 10.13 in non-English locales
  • Regression in 9.2: Node detail dialog did not wrap long lines
  • Class tracker: In snapshots, a wait cursor was always displayed on the view
  • When opening a snapshot and choosing the deobfuscation option in the file chooser, choosing "None" as the deobfuscator prevented opening of the snapshot
  • Fixed a StackOverflowError when opening the profiling settings dialog on Linux with a non-default look and feel
