I am running JBoss 4.2.3 with JBoss Messaging 1.4.2.GA-SP1

This is related to Container Managed Transactions and handling Application Exceptions within EJBs and MDBs.

The following are the exceptions I use:
MyRetryException - Extends Exception
MyEJBRetryRuntimeException - Extends Runtime Exception. Annotated with @ApplicationException ( rollback = false )

The following represents a scenario I am testing.

public class myMDB implements MessageListener
{
 @EJB
 MyEJB myEJB;

 public void onMessage( Message msg )
 {

 try
 {
 myEJB.process(); // uses the transaction from the MDB
 }
 catch ( MyEJBRetryRuntimeException e )
 {
 myEJB.handleException( e ); // starts a new transaction
 throw e; // I want this message to be redelivered
 }
 }
}

In myEJB...

@TransactionAttribute( TransactionAttributeType.SUPPORTS )
public void process()
{
 try
 {
 throw new MyRetryException ("test");
 }
 catch ( MyRetryException e )
 {
 throw new MyEJBRetryRuntimeException(e);
 }
}

@TransactionAttribute( TransactionAttributeType.REQUIRES_NEW )
public void handleException( Exception ex )
{
 Connection conn = datasource.getConnection(); <-- throws an exception.

}

The handleException method tries to obtain a jdbc connection but throws the exception: javax.resource.ResourceException: Interrupted while requesting permit! Waited 0 ms.

According to http://www.jboss.org/community/docs/DOC-10001 it seems that i would get this error when a transaction is rolled back but I am throwing an ApplicationException with rollback = false. Is there something I'm not doing right? Any help would be appreciated.
