Comment 5 Alexander Kouznetsov 2007-11-16 18:47:07 UTC

Reproduced with
Product Version: NetBeans IDE 6.0 RC1 (Build 200711160000)
Java: 1.6.0_03; Java HotSpot(TM) Client VM 1.6.0_03-b05
System: Windows XP version 5.1 running on x86; Cp1251; ru_RU (nb)

Tried to start customized memory profiling for JBossTest application: allocation, record stack traces, limit stack depth
to 2 frames, don't run garbage collection, enable threads monitoring. After a long instrumentation phase Profiler
complained that profiled application doesn't respond. Had to cancel profiling.
