I don't actually get a stacktrace because I test the Object before attempting
to cast it:
| public void onMessage ( final Message message )
| {
| if( message instanceof ObjectMessage )
| {
| ObjectMessage objectMessage = (ObjectMessage)message;
| Serializable payload;
| try
| {
| payload = objectMessage.getObject();
| if( payload instanceof TypedData )
| {
| m_incomingQueue.add( (TypedData)payload );
| }
| }
| catch( JMSException e )
| {
| m_handler.onConnectionException( new ConnectionException( e
) );
| }
| }
| }
|
The issue is that the payload is a TypedData Object, but loaded using the
ClassLoader of the topic producer, not the subscriber. In this particular
instance my receiver is instantiated inside of a .war file (nested in a .ear
file), but it appears to also happen when the receiver is loaded outside of the
.war as well (e.g. instantiated from a Service Bean in the EJB context).
After modifying the code to naively cast the payload to the TypedData class
without checking for type I receive the following:
| 13:20:14,624 ERROR [ClientConsumer] RuntimeException was thrown from
onMessage, 20345880406507537 will be redelivered

Let me know if there's anything else that would be helpful.
