> Create a simple receiver, but do not place it within a Transaction boundary; shut down the server; look up the tables and you will see all the messages are still in the Messages and MessageRef tables.
> =========================================
> Observations using a debbuger reveal the following:
> =========================================
> Looking over the org.jboss.resource.adapter.jms.JmsManagedConnection the setup method will always call createXAQueueSession() and create an XAQueconnection as transacted and Session.SESSION_TRANSACTED.  That being the case, non-XA Queues have no message-deletion problems with the current version (RC4) because the API removes all messages that are "not transacted and (!ack==1). I am guessing that using XA is problematic because the persistence layer is expecting manipulation of the transacted XASession--which for some reason is not working in this version of Messaging. More specifically, I suspect that when MDBs are tested you are not seeing this problem because the container is doing needed magic to manage the XASession transacted state, and therefore everything works fine therein. And consequently, when operating as a non-MDB client, AKA a simple Receiver, there is something missing in the equation ergo the problems that I have been reporting regarding the ClickCommerce applications which use Receivers and not MDBs.  
> Work-around: None; the strategy for my team is to NOT use an XAQueueConnection while waiting for a fix.
