An Openwire client does not honor the max-delivery-attempts set on an Address. This allows a message to be delivered multiple times if the client never Acks the message. The Openwire client handles redelivery client side, so the client can track if the message has been redelivered, however if the client only makes 1 attempt to receive the message and disconnects, followed by the consumer being recreated, this cycle could be infinite as the message never gets the redelivered flag set.
