I just tried to replicate the scenario you described and the test passed without a problem. I have tried with both transactioned and non transactioned. I was wondering if you have your client on localhost (same IP as the JMS server), and if you don't have any restriction on network, on that case you would need to add few parameters on your client VM: http://labs.jboss.com/file-access/default/members/jbossmessaging/freezone... It would help if you had an example of how you are doing this. (A testcase would really helps). As the scenario as you described didn't fail.
