Description tboerkel 2007-10-25 07:27:33 UTC
[ BUILD # : 200710212201 ]
[ JDK VERSION : 1.6.0_03 ]

I am attaching the profiler to the target VM via local dynamic attach
(Java 6.0).

If I use Memory or CPU profiling, the target VM crashes shortly after
attach or a little while later.

This also happens with VisualVM. So, it is either a profiler issue or
a JDK issue.

Attaching crash log.

Comment 2 J Bachorik 2007-10-25 08:32:41 UTC
this is a duplication of the issue #88776
a known workaround is to start the profiled application with -Xshare:off argument

*** This issue has been marked as a duplicate of 88776 ***
Comment 3 tboerkel 2007-10-25 09:12:37 UTC
Thanks, this works as workaround. However, CPU profiling does not work after attach. I get no live results and cannot
take snapshots. Not even for threads that are being started after attach. Is this a known problem? Shall I file a new issue?
Comment 4 Alexander Kouznetsov 2007-10-29 19:11:59 UTC
Try to:
1) Enable "Profile Threads started after entering any of root methods" Advanced Settings option
2) Open profiled application sources in NetBeans as project and select it in Attach dialog.

If this doesn't help then please file new issue.

I did: Issue #120038. And it is already fixed. :-)
