* This is a bit of a hack for backwards config compatibility since we no longer want to start the broker
* using the JMSServerManager which would normally deploy JMS destinations. Here we take the JMS destination
* configurations from the parsed JMS configuration and add them to the core configuration.
*
* It's also important here that we are adding them to the core ADDRESS configurations as those will be
* deployed first and therefore their configuration will take precedence over other legacy queue configurations
* which are deployed later. This is so we can maintain support for configurations like those found in the
* bridge and divert examples where there are JMS and core queues with the same name (which was itself a bit
* of a hack).
*
* This should be removed when support for the old "jms" configuation element is also removed.
