Gili commented on NETBEANS-359:
-------------------------------
I am seeing this issue extremely frequently (over 50% of the time I attempt to
profile). Can anyone else reproduce this on their end or is it specific to my
project?

> and the profiling session subsequently hangs indefinitely.
> Repro steps:
> # Open Maven project
> # Start profiling session
> # Profile -> Methods
> # Profile: Focused (instrumentation): Selected Classes
> # Select a project in the current project
> # Launch profiling session
> # 3-5 seconds into the session, the exception thrown.
> # Once you are in this bad state, hitting the "Re-run the goals" button in
> the Output Window causes the bug to keep on appearing 100% of the time. If I
> stop and manually run the profiler again the problem is less likely to return.
