Me neither. Yet I think it's correct.
Ask yourself for which purpose in Java-to-Java communication you would need such heavy web service implementation as SOAP (standard? marketecture over architecture?). In Java-to-Java there are plenty much lighter alternatives - just look at Spring remoting.
We really need SOAP when we communicate with non-Java client/server - interoperability. And what if that non-Java platform does not support all/some features of OOP including inheritance? So SOAP web service is the lowest and heaviest possible denominator. Use concrete classes instead - exact return types.
