Martin Ritchie reopened QPID-1864:
----------------------------------


Hi Rafi, The new test you added is highlighting a race condition in the 0-8 
code path.

This is the error log:
Exception in thread "Dispatcher-Channel-1" java.lang.IllegalStateException: 
dispatcher is not started
        at org.apache.qpid.client.AMQSession.dispatch(AMQSession.java:2696)
        at 
org.apache.qpid.client.message.UnprocessedMessage.dispatch(UnprocessedMessage.java:55)
        at 
org.apache.qpid.client.AMQSession$Dispatcher.run(AMQSession.java:2827)
        at java.lang.Thread.run(Thread.java:619)

I'll attach the full .out file aswell. Can you take a look and see if the 0-10 
change you made would also apply to 0-8?

Cheers

> On rollback, the java client sometimes releases messages from the dispatch 
> thread. These messages are released in an unpredictable order relative to the 
> messages released from the main thread. Also, the messages released from the 
> BMC.rollbackPendingMessages() are released individually and in the opposite 
> order of what would preserve queue order in a single consumer scenario.
