Rajith Attapattu commented on QPID-3625:
----------------------------------------
Keith, after some investigation we've determined that CLIENT_ACK is not correct
and AUTO_ACK is the easiest way to handle the general case.
For the specific JCA case we are exploring the possibility of using CLIENT_ACK
by modifying the ack mode runtime. Weston will produce a patch for this shortly.
Since the change is reversed the test cases should now all pass.
> XASessionImpl Incorrectly sets Session acknowledge mode to AUTO_ACKNOWLEDGE
> when it should be CLIENT_ACKNOWLEDGE

> When using distributed transactions (XA) message acknowledgement needs to
> occur prior to the XA transaction being started in order to consistently
> support the two phase commit protocol. In order for this to correctly occur,
> the XASessionImpl, a non-transacted Session (i.e. non JMS transacted session)
> should be configured to use CLIENT_ACKNOWLEDGE as this is the only mode that
> supports explicit message acknowledgement which again, is required to
> correctly participate in the distributed transaction.
