Comment 3 Jiri Sedlacek 2011-10-06 11:00:50 UTC 
Steps:

 - clean userdir or NO profiler window open (like Control Panel, Telemetry etc.)
 - start cpu profiling, default settings
 - once the profiling session is FULLY started, open the live results

Doesn't seem to be reproducible with the Control Panel window persisted & opened from the previous IDE session.
Comment 4 Jiri Sedlacek 2011-10-06 11:03:24 UTC 
Caused by TargetAppRunner.getDefault() == null at DrilldownContributor.java:177.

Might be related to http://hg.netbeans.org/profiler-main/rev/29cb4f37f1aa. Jardo please check whether null default TargetAppRunner is the correct behavior.
