> It will happen when one thread is in a loop to try to connect the broker, in the meanwhile another thread calls the stop action.
> Thread A (in the run() method) holds the connectWork, and requires the shutdownMutex when it is notified by the notifyAll action by ThreadB.
> Thread B (in the stop() method) holds the shutdownMutex, and requires the connectWork in the disconnect method.
> I move the disconnect() invocation out of the synchronized (shutdownMutex) block, it works well.
> Thanks !
