> A defect in AsyncAutoCommitTransaction means that occasionally messages delivered by a non-transactional JMS are seen to be enqueued out-of-order and therefore delivered to a consumer out of the expected order.  
> It is this problem that underlies QPID-4014, although as I think this problem is wider than ConflationQueues, I am raising this separately.
