When a Remote interface has a method which takes a Serializable interface
as an argument, rmic generates wrong code.

E.g.
public interface Hello extends EJBObject {
    public void handleEvent(EStoreEvent se) throws RemoteException;
}
public interface EStoreEvent extends java.io.Serializable {
}

rmic generates an _EStoreEvent_Stub, and in the tie for the HelloImpl object,
it generates wrong unmarshalling code for the handleEvent method.
(it generates read_Abstract_Interface(_EStoreEvent_Stub.class) ....)
Basically it is treating EStoreEvent as a Remote object instead of
as a Value object.
