/**
 * This is a test Handler which interacts with the TestService below in
 * order to test header processing.  This one runs before the TestHandler,
 * so when the TestHandler throws an Exception (triggered by a particular
 * header being sent from TestOnFaultHeaders), the onFault() method gets
 * called.  In there, we get the response message and add a header to it.
 * This header gets picked up by the client, who checks that it looks right
 * and has successfully propagated from here to the top of the call stack.
