                 Key: QPID-1677
                 URL: https://issues.apache.org/jira/browse/QPID-1677
             Project: Qpid
          Issue Type: Improvement
          Components: Java Client
    Affects Versions: M4
            Reporter: Rajith Attapattu
            Assignee: Rajith Attapattu
             Fix For: M5


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).
