When there is an MDB deployed and I send a single message to the queue this MDB listens to, the server hangs on during shutdown. I believe this is the reason:

17:35:29,181 WARN [org.jboss.messaging] (MSC service thread 1-3) failed to destroy jms queue: TasksQueue: HornetQException[errorCode=104 message=Cannot delete queue jms.queue.TasksQueue on binding jms.queue.TasksQueue - it has consumers = org.hornetq.core.postoffice.impl.LocalQueueBinding]

The MDB throws and EJBException in the onMessage() method and the message ends in DLQ. I'm not sure if this is related to the problem. If needed I could create a reproducer that I can provide, but it is not ready at the moment.
