>             Project: JBoss Messaging
>          Issue Type: Bug
>    Affects Versions: 1.4.1.beta1, 1.4.0.SP3_CP01
>            Reporter: Clebert Suconic
>         Assigned To: Tim Fox
>             Fix For: 1.4.0.SP3.CP02, 1.4.1.beta2

> / You open a Transacted Session
> Session sessionA = ..... ;
> // You create a Producer on SessionA
> MessageProducer producerA = .....;
> // You create a Consumer (with a messageListener on SessionA)
> MessageConsumer consumerA = ....
> setMessageListener(....);
> producerA.sendMessage(....);
> sesssionA.commit();
> // consumerA will process the message
> // consumerA will call sessionA.commit();
> - The problem here is: The message is arriving during sessionA.commit(); (after commit was called, before commit was completed)
> - By the time sessionA.commit is finished, a new transaction will be opened.
> - The message arrived on the old completed transaction, hence the message will never be acked.
