I don't think it should, rolling back the transaction has no impact on how things end up really. The original message cant be consumed, the next wont be produced, and nothing has 'gone wrong' with the transaction itself. > Another question is whether you would permit the client to commit such a > transaction. > I think commit should fail, but I also dont think its a big deal if it doesnt in most cases (but Rob's DLQ point is fair) given the end state. At the end of the day, if queues are being deleted mid use, neither side can independently deal with it easily and things are likely to get a bit stuffed. > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [email protected] > For additional commands, e-mail: [email protected] > --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
