Error description

MQServer is added as a member of WebSphere Application Server
Service Integration Bus and destinations are created on
the MQServer.When "Receive Exclusive" and "Maintain strict
message order" properties are enabled on the destinations,
java.lang.ClassCastException occurs.
Following errors are written to SystemOut.log:

CWSID0009E: Destination XXX cannot be created.
CWSIP0062E: The destination XXX with UUID nnnnnnnnnn could
not be recovered due to a possible WCCM configuration error
CWSIK0015E: The destination XXX was not found on messaging
engine
ZZZZ.

FFDCS are produced with the following stack:

****************************************************************
When MQServer is added as a bus member to a SIBus, the MQ
destinations are backed by the SIB destinations created on the
SIBus. The properties such as "receiveExclusive",
"receiveAllowed" and "maintainStrictMessageOrder" set on these
SIBus destinations through administrative console are
propagated to the actual MQ destinations. Administrators can
be able to modify the settings of these properties. When
"receiveExclusive", "receiveAllowed" and
"maintainStrictMessageOrder" are enabled on these SIBus
destinations by checking the corresponding checkboxes on the
administrative console, a ClassCastException is thrown in the
messaging engine logs. This exception is also thrown when the
properties are enabled and the environment is restarted.
Later, the destinations are marked as unavailable.
The exception is thrown due to a code defect. When
"receiveExclusive" is enabled,the code first tries to obtain
the consumer manager related to the SIB Destination which is
backing the MQ destination. The consumer manager obtained is
not a ConsumerDispatcher but RMQConsumerManager. Due to wrong
casting this results in the java.lang.ClassCastException.
Similary, the java.lang.ClassCastException occurs when the
value of "receiveAllowed" is changed.

Problem conclusion

The defect has been fixed to properly cast the obtained
consumer manager into RMQConsumerManager and use it further.

The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.31, 8.0.0.8 and 8.5.5.2.  Please refer to the
