Comment 2 Jiri Sedlacek 2012-11-05 14:32:00 UTC
Profiler options are in Options | Java | Profiler. If you can't see the Profile menu, your IDE is probably incorrectly installed - make sure you're running with a clean user&cache directory.

The exception was thrown from Attach Profiler action, not Profile action as mentioned. I assume you've invoked Profile or Attach Profiler before. Works fine on my side, not reproducible. Please provide detailed steps if you happen to get the exception again.

Implemented a workaround to prevent the NPE, can't do more without a reproducible test case: http://hg.netbeans.org/profiler-main/rev/da76d8aa2fa7

Integrated into 'main-golden', will be available in build *201211060001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
Changeset: http://hg.netbeans.org/main-golden/rev/da76d8aa2fa7

Log: Bugfix #221267 - prevent the NPE probably caused by incorrect synchronization of SPT.cleanup(), not reproducible
