The number of existing tests fails sporadically in DUPS_OK mode by relying on fact that method AMQSession.getQueueDepth(AMQDestionation) returns the correct result.
In case of DUPS_OK, a message acknowledgment can be sent as part AMQSession.getQueueDepth(AMQDestionation) before sending QueueQuery command.
Currently session does not sync between sending acknowledgments(MessageAccept) and QueueQuery commands.
As result of it QueueQuery command results can be returned before MessageAccept is processed on the broker. In this case QueueQuery results might contain incorrect messageCount value.
