Description matusdekanek 2009-05-15 12:39:48 UTC 
Build: NetBeans IDE Dev (Build 200905121401)
VM: Java HotSpot(TM) Client VM, 11.0-b16, Java(TM) SE Runtime Environment, 1.6.0_11-b03
OS: SunOS, 5.11, x86

User Comments:
matusdekanek: waiting for the sample aplication (netbeans module|paint application) to end

GUEST: Happened when profiling a simple program with a recursive call (100000 deep). Probably the depth of the recursion caused the problem.

Reassigning to profiler
Comment 3 Jiri Sedlacek 2009-06-08 12:25:46 UTC 
Not for 6.7.

As a workaround increasing the stack size should help: -Xss (http://forums.sun.com/thread.jspa?threadID=187774&forumID=27).
Comment 4 mzav 2011-07-04 14:04:14 UTC 
I have similar problem when I try to profile a java code from http://developers.slashdot.org/story/11/06/15/0242237/C-the-Clear-Winner-In-Googles-Language-Performance-Tests

There is a little difference in my scenario - I do not see the exception.
I use -Xss20000k.
Program is normally terminated (according to my traces), CPU activity stays 0%, but I never have results of profiling. Profiler is reported as "running...".
I've detected that there is a recursive function in the code - doDFS - with very big depth. When I artifically limit the depth (1000) - profiler works.

This problem exists both on 6.9 and 7.0.1 RC1

Could you advise please.
Thanks,
Michael.

Fixed in http://hg.netbeans.org/profiler-main/rev/4afb0572131e

Replacing recursion based RuntimeCCTNode visitor implementation in favor of linearized hierarchy processor.
