NullPointerException during afterDelivery phase of MDB running in Sun AS 8.1

I have setup an environment using Sun MQ 3.6 where the XAQueueConnectionFactory
and destination are registered into a directory server.

Using the genericjmsra to access the queue via lookups for the administered
objects in ldap results in the following exception being reported in the AS8.1
log files during the afterDelivery phase processing following an MDB consuming a
message.

As of yet I do not know the full impact that this exception will have on a
production system but at the very least it should not be reporting a null exception.
