Attachment: patch-1397-2.txt
Patch makes the method JvmRunner.kill() synchronized so that if kill is
in-progress, the caller will wait till kill completes. Making the method
JvmRunner.kill() synchronized is fine because all the external callers are
already synchronized on JvmManager. Now patch makes it synchronized on
JvmRunner also.

observed in the TT/JT logs when a task fails. The situation is aggravated
when the taskcontroller.cfg is not configured properly. Below is the
exception obtained:
