Ok, we're on the same page. This is indeed weird. We have a JUnit test BytesMessageTest.testRedelivery() which checks this use case and this test pass for JBM 1.4.0.SP3. Our test does not use a MessageListener but I don't think it'd affect the message behaviour. Can you write a unit test which reproduces your problem in your environment?
