Description Alexander Kouznetsov 2007-03-15 16:37:32 UTC 
Profiler 070314
NetBeans IDE Dev (Build 200703141900)
1.6.0; Java HotSpot(TM) Client VM 1.6.0-b105
Windows XP version 5.1 running on x86
ru_RU (nb); Cp1251

Steps to reproduce:
- Insert Reset Results and Take Snapshot Profiling Points on the same line of
Anagram Game application (first line of nextTrial...() method body)
- Start Analyze Performance Task with Entire Application and Profile Only
Project Files options set
- Press Next Word button in Anagram Game application
- RESULT: NPE is thrown and PPs stop to work. Trying to perform some other
actions will cause IDE to hang. And it can't even be exited correctly.

Comment 7 Alexander Kouznetsov 2007-03-26 21:51:36 UTC 
Failed to verify with Profiler 070323
Always get the following exception:
com.sun.tools.profiler.results.cpu.CPUResultsSnapshot$NoDataAvailableException

com.sun.tools.profiler.results.cpu.CPUResultsSnapshot.<init>(CPUResultsSnapshot.java:95)

Lowering the priority since IDE doesn't tend to hovering.

Comment 9 J Bachorik 2007-03-27 09:21:01 UTC 
The observed behavior is caused by the fact that you place both PPs on the
beginning of the line. Thus virtually cleaning all results and immediately after
that taking snapshot of no results. You should place "ResetResults" on the line
beginning and "TakeSnapshot" on the line end. That way you will get a snapshot
of results generated by the selected line.
I still do insist that the issue filed here originally has been fixed. I'm
creating a new issue #99078 for the problem you've described
