 * All throwables caught on the server are wrapped with a RemoteTestException
 * and rethrown.  On the client side the exception is caught, and if the 
 * server side exception is an instance of AssertionFailedError, it is
 * wrapped with an instance of this class and rethrown. That makes the 
 * exception an instance of AssertionFailedError so it is reconized as 
 * a failure and not an Error.
