Attempted to profile (CPU) all of the application with this result.

I also tried using a filter (inclusive for org.apache ) and it started 
profiling but died with the same null pointer exception a short while later.
Comment 1 Jiri Sedlacek 2006-08-15 20:49:15 UTC 
Could you please attach NetBeans logfile (messages.log) and provide steps/simple
app how to reproduce?
Comment 2 J Bachorik 2007-01-09 08:18:00 UTC 
Could you, please, verify the described behavior on the current profiler build
(M4 or upcomming M6)? And also, plz, provide steps/simple app to reproduce
and/or thread dump.
Comment 3 J Bachorik 2007-03-23 16:06:42 UTC 
should be changed by rewrite of CCT building algorithm
plz, recheck in M8 and reopen if it's still applicable
Comment 4 Maksim Khramov 2007-11-01 12:21:21 UTC 
verified in build 200710310000
