http://www.gxdeveloperweb.com/Forums/Forum-GX-WebManager-Usage/Jprofiler.htm Hey guys, I'm having trouble profiling webmanager with JProfiler. One of our WCB is leaking memory and we want to find out where. But I keep getting the below stacktrace on boot. Has anyone got JProfiler to work with GX? Any help is appreciated.
