 /**

  * <p>
  * The JAX-WS spec always use a singleton instance
  * to serve all the requests, but this hook provides
  * a convenient way to route messages to a proper receiver.
  *
  * <p>
  * Externally, an instance of {@link InstanceResolver} is

  *
  * <h2>Possible Uses</h2>
  * <p>
  * One can use WS-Addressing message properties to
  * decide which instance to deliver a message. This
  * would be an important building block for a stateful
  * web services.
  *
  * <p>
  * One can associate an instance of a service
  * with a specific WS-RM session.
