Update I can now reproduce the error in a small test program. All I did was increase the messaging from 2 to 4 messages and fiddle a bit with the JPA code. The fiddling required seems to be different depending on whether I use OpenJPA or EclipseLink.
I am beginning to suspect that I might be bitten by this bug, fixed in ActiveMQ 5.6.0: https://issues.apache.org/jira/browse/AMQ-3465 Now I am itching to try a newer ActiveMQ than the bundled one. Is this possible? I naively tried replacing the activemq-core jar but that just gave me "peer did not send his wire format". -- Björn Danielsson Cuspy Code AB
