> There is a common FAQ about how to keep message ordering in the event of failure (i.e. a NACK or transaction rollback).
> JMS gives no such guarantees.
> However, we could give that guarantee at the expense of throughput.
> Basically what we need to do is not allow anybody to receive() a message until the single message (or group of messages
> in the same transaction) that has already been received is either nacked or acked.
> Once the nack (rollback) comes from the client that has the "checked out" message it will be reinserted back into the Queue
> at the top of the list and then we allow the next receive() to run. 
> Meaning it always the nacked message and can't get any other message until the top message is acked.
