Timothy Bish closed AMQNET-332.
-------------------------------
Resolution: Cannot Reproduce
I haven't been able to reproduce this. If you find a test case that can show
this happening I'd be happy to dig further but so far I can't create any
scenarios where this happens.
> Rollback fails with Null Reference

> I call rollback several times and retries occur as expected. At some point,
> the rollback fails and I no longer receive the message. I would like to give
> information on how to produce this but it just happens randomly. I'm hoping
> from the stack trace, you might have an idea of the cause.
> There are no errors logged on the server. This error is on the client side:
> Message: Unable to rollback transaction.
> Stack:SessionExecutor.Dispatch => MessageConsumer.Dispatch =>
> MessageListenerDelegate.OnMessage
> System.NullReferenceException: Object reference not set to an instance of an
> object.
