Description
currently you can call ActiveMQDestination createDestination("",ActiveMQDestination.QUEUE_TYPE) to create a queue with no name.
while this doesn't seem to be an issue at first...if you are using mKahadb, ActiveMQ will fail to restart after this queue/store directory are created.
the web console already prevents this, we should prevent this from other entry points to this API (QueueView.moveMessagesTo() from JMX in my case)...
