weldon washburn commented on HARMONY-3582:
------------------------------------------

I tried running gc.MultiThreads on the latest svn head on my windows laptop.  I get the following
error:

C:\Documents and Settings\weldon\My Documents\important\misc>c:\t_harmony\trunk\
working_vm\build\deploy\jdk\jre\bin\java -cp c:\"Documents and Settings"\weldon\
"My Documents"\important\misc;. gc.MultiThread

I built a simple MegaJoin.java test and attached it to this JIRA.  On my windows laptop, it
gives basically the same error as the above.  See below.  Does anyone see this on their laptop?
 Also, both MegaJoin and also gc.MultiThreads work fine on Linux.

I can repro the hang in the debugger as well. Breaking in with the debugger shows a deadlock
where the shutdown thread is blocked trying to acquire a critical section that was probably
not cleanly released by a terminated thread.
