With JBossMQ Beta1, i stop a client receiver while it is receiving messages from a queue (connection is not closed properly). Then i create another receiver on the same queue and a sender sends messages to that queue. The receiver does not receive the first message because it is sent (unsuccessfully) to the receiver that was previously crashed. Exception on server side: "Client Consumer could not send messages to a receiver." "JMSServer : the connection to client failed."
