This method retrieves bundle context . There is a requirement to lookup the DS Services Registry during recovery . Any bundle context will do for the lookup - this method is overridden in the ws . tx . embeddable bundle so that if that bundle has started before the tx . jta bundle then we are still able to access the Service Registry .

configureReplyDestinationFromRoutingPath Configure the ReplyDestination from the ReplyRoutingPath . The RRP from the message is used as the FRP for this Reply Destination so most of the function is performed by configureDestinationFromRoutingPath . This method keeps hold of the bus names as well as the destination names .

This method is called to request a shared lock . There are conditions under which a shared lock cannot be granted and this method will block until no such conditions apply . When the method returns the thread has been granted an additional shared lock . A single thread may hold any number of shared locks but the number of requests must be matched by an equal number of releases .
