I've implemented a version of this in the AS testsuite (trunk and Branch_4_2). See org.jboss.test.classloader.leak.clstore.LeakAnalyzer. Added an overloaded exploreObjectReferences that takes a parameter to indicate if it should produce a condensed format report. If not condensed, reference chains that would survive on the condensed report are shown in bold, with the ultimate root in red. Not sure at this point if the condensed part works right, but the bold/red bit does, so I know I can make the condensed work simply by not printing nodes if they wouldn't be bold. I'll do that sometime later. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4027012#...
