Until successful asynchronous processing strategy.
It will return successfully to the flow executing the router once it was able to
store the message in the object store.
After that it will asynchronously try to process the message through the internal route.
If route was not successfully executed after the configured retry count then the message
will be routed to the defined dead letter queue route or in case there is no dead letter
queue route then it will be handled by the flow exception strategy.
Method used to perform any initialisation work. If a fatal error occurs during
initialisation an InitialisationException should be thrown,
causing the Mule instance to shutdown. If the error is recoverable, say by
retrying to connect, a RecoverableException should be thrown.
There is no guarantee that by throwing a Recoverable exception that the Mule
instance will not shut down.
