ApplicationNotReadyException - if thrown by the listener, Messaging (the client-side
MDB) will attempt to redeliver this message. Thus, an
application can throw this exception in situations
where it is not yet ready to process messages.
There is a nominal retry interval of a few seconds
between redelivery attempts. The number of retry
attempts is configurable via the client-side MDB's
MaxDeliveryCnt configuration property.
