[Design of JBoss Profiler] - Crash when stopping JbossProfiler 2.0.Beta 1
by pisce
Hello,
I'm currently evaluating the JBoss profiler 2.0.Beta 1, and after one successful attempt, I keep getting the folowing error when stopping the profiler:

I followed the readme file for installing and executing the profiler. Any hint/advice/workaround?
