[AMQ7, openwire, exclusive consumer] AMQ6 openwire clients using exclusive consumer, do not behave the same with an AMQ7 broker

In AMQ 7, setting the maximum number of consumers for a queue to one does not work the same as an "exclusive consumer" in AMQ 6. In AMQ 6, an exclusive consumer means that one consumer will get all the messages. Any other consumers are still registered, just not consuming messages. When the current exclusive consumer leaves the queue, another consumer becomes the exclusive consumer. In AMQ 7, if you set max-consumers = 1 for a queue, when this limit is reached, the broker returns a "AMQ119200" error and does not allow any new consumers to join the queue.
