/**
 * This tests that it is possible to use the more advanced function allowed by the WS-Addressing
 * specification to redirect responses. This test sets up 2 services, MultiHopRedirectService1 and
 * MultiHopRedirectService2. MultiHopRedirectService1 echos the XML it receives to
 * MultiHopRedirectService2, adding the original ReplyTo. MultiHopRedirectService2 then echos the
 * XML to the orignal ReplyTo, setting the RelatesTo to the messageID of the original request
 * message to allow the client to correlate the message.
 * <p/>
 * The clearly only works if the client is using a separate listener (which the client in the test
 * does)
