webrev: http://cr.openjdk.java.net/~dholmes/8146616/webrev/
We encountered a bug with the Solaris Studio 12u4 compiler that causes a
destructor not to be called when leaving a block, and so leaves a system
monitor locked. A workaround is to introduce an explicit local scope:

assert(_before_exit_status == BEFORE_EXIT_DONE, "invalid state");

case BEFORE_EXIT_DONE:
- return;
+ // need block to avoid SS compiler bug

+ }
}
Thanks,
David
