Comment 1 Vince Kraemer 2008-06-20 23:08:35 UTC 
this seems a bit contrived... but...
Comment 2 Vince Kraemer 2008-10-25 03:55:15 UTC 
this looks like it is something to work for 7.0 now...
Comment 3 Vince Kraemer 2008-11-14 20:55:52 UTC 
This also applies to 6.5.

The JVM is waiting for the profiler to attach and we call stop-domain... which triggers the exception.

Need to look for a way to tell the agent to die quietly.

Please update this issue with necessary info about how the GF plugin can shutdown the GF JVM that is waiting for the IDE
to attach in an orderly fashion.

Then feel free to re-assign it back to me.
Comment 4 J Bachorik 2011-10-05 17:29:36 UTC 
The exceptions are totally harmless. Unfortunately, there is currently no way to gracefully shut down a JVM waiting for the profiler to attach.

While I was evaluating this issue I noticed something else, may be even more important - it is not possible to restart or stop the GF instance while it is waiting for the profiler client to attach. The menu items are grayed out.
Comment 5 Vince Kraemer 2011-10-31 22:11:32 UTC 
cannot reproduce with 3.1.1 and 7.0.1...

marking as worksforme, since I do not know which code change resolved this issue
