Subject Re: Java JMS acknowledge and prefetech
Date Thu, 20 Feb 2014 15:33:30 GMT
OK - I have found the issue, it is indeed a bug in the Qpid client  :-(

The issue is in client acknowledge where, if you only have one message to
acknowledge, it will actually acknowledge all of the prefetched messages.
 I shall check in a fix presently.  If you use other acknowledge modes or
if you are acknowledging more than one message then you would not see this

Apologies for this.
