Description Jiri Sedlacek 2012-01-23 14:51:45 UTC 
Product Version: NetBeans IDE Dev (Build 20120123-de5ca11607e2)
Java: 1.6.0_30; Java HotSpot(TM) 64-Bit Server VM 20.5-b03
System: Windows 7 version 6.1 running on amd64; Cp1252; en_US (nb)

Steps:

 1/ Started profiling AnagramGame, CPU, Profile application, default roots, Profile all classes
 2/ Didn't open Live Results, clicked Stop profiling icon in Profiler Control Panel shortly after starting the profiling session

The following exception has been thrown into profiled app Output. Probably not easily reproducible. Profiling session has been terminated correctly, profiled application has been stopped.
