> If VH housekeeping thread experiences an unexpected exception, the current implementation (uses a ScheduledThreadPoolExecutor) neither reports the exception nor causes the Broker to shutdown the Broker.
> Note that ScheduledThreadPoolExecutor do not use the uncaught exception handlers, we need to intercept #afterExecute.
> http://docs.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/ThreadPoolExecutor.html#afterExecute(java.lang.Runnable,%20java.lang.Throwable)
> (This came to light during the investigation of QPID-6607.  QueueRunner threading is now performed by the housekeeper and its exceptions were being swallowed silently).
