Error description

When using WS-Reliable Messaging to send a message in a two
phase transaction, the following exception occurs:

As a result the two phase transaction rolls back.

* RECOMMENDATION:                                              *
****************************************************************
The problem is caused by an incorrect state transition in the
underlying Service Integration Bus resource manager
transaction.  Due to a programming error, that transaction had
started preparing as if it were in a one phase transaction
before the two phase transaction prepare call was received
from the transaction manager.  This causes the
IllegalStateException and so the two phase transaction rolls
back.
This does not result in a non-atomic outcome for the
transaction because all resources involved in the two phase
transaction rollback, including the WS-Reliable Messaging
resource.

Problem conclusion

This APAR corrects the programming error to ensure correct
intereaction between WS-Reliable Messaging and the underlying
Service Integration Bus transaction, and the two phase
transaction proceeds as expected.

Before uninstalling this APAR or a fix pack that contains this
APAR it is recommended that any sequences are quiesced.  If
not there is a chance that until the APAR is reapplied any
sequences that existed prior to the uninstall cannot be
deleted.  WS-Reliable Messaging functionality is unaffected by
this.  Simply the sequence cannot be deleted until the APAR is
reapplied.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.23 and 8.0.0.4.  Please refer to the Recommended
Updates page for delivery information:
