HeapAnalyzer

HeapAnalyzer is a comprehensive software utility that you can use to analyze possible Java heap leaks. It is not wrapped up in a setup pack, as it only needs Java to run.

You can extract the program files to any part of the hard disk and just click the executable to run. Another possibility is to save HeapAnalyzer to a USB flash drive or other type of removable storage unit, in order to run it on any PC with minimum effort, as long as it has Java installed.

More importantly, the tool does not create new entries in the Windows registry or Start menu, thus leaving no traces behind after removal.

The GUI is made from a regular window with a plain and simple layout, where all options are neatly organized in menus and the toolbar. HeapAnalyzer is able to open heap dumps with the TXT, TXT.GZ, PHD and HA format. In case a file is not identified as valid by the app, you can select a format to force analysis, between IBM classic/text, IBM PHD, HPROF binary and HPROF text.

It is possible to view roots, the gaps distribution chart, the heap dump tree sorted by total size, or list of objects or types sorted in a random order, sort gaps between objects by size, as well as to search for names and addresses. The status bar may be hidden, while the console window can be enabled.

You can specify the maximum number of sub trees and super trees, minimum total size drop for search (in bytes), default directory, verbose mode, as well as interface look and feel, among others.

The tool does not put a strain on computer performance, since it runs on low CPU and RAM. It has a good response time and works well, without triggering Windows to hang, crash or pop up error messages. HeapAnalyzer serves its purpose.
