    Description

      When the main thread calls ResourceManager$SchedulerEventDispatcher.stop() it grabs a lock on the object, kicks the event processor thread, and then waits for the thread to exit. However the interrupted event processor thread can end up trying to call the synchronized getConfig() method which results in deadlock.
