No it won't.
There are two reasons:
1) The ejb-spec says that the create-method must return the
remote-interface.
2) The jls (java language spec) says that a method with signature "A foo()"
cannot be shadowed by a method "B foo()" even if B is a subclass of A. This
a very stupid fact, since it is completely type-safe (if B is a subclass of
A), according to Bertrand Meyers' Design By Contract.
