>
> In order for the producer to not replay the messages again (during failover) 
> and prevent duplicates,we need a way for the JMS client to sync on every 
> publish. 
> To faciliate this, I have propose a System/Connection URLproperty called 
> sync_publish={persistent|all} which supercedes sync_persistent.
> (sync_persistent is deprecated but supported for a few releases with a 
> warning printed if used).
> In order to provide exactly-once semantics between a single JMS 
> publisher-consumer pair (when using AUTO_ACK on the consumer) we need to 
> publish synchronously and ack synchronously (QPID-1106).
