Do you perhaps have more than one MessageBrokerServlet configured in the
same web application? The hibernate assembler is trying to do:
dataDestination =
DataDestination.getDataDestination(destinationId);
which is using the default MessageBroker.getMessageBroker() method to
try and look up the destination for this data type. For some reason, it
is probably finding the wrong MessageBroker. The hibernate assembler
probably should be getting the message broker id of the message broker
that initializes it and use that to look up the destination.

Rollback seems to be the only option at this point.
