MyStateful should extend javax.ejb.EJBObject to become an EJB2.x Remote Interface. Technically, @Remote is to designate business interfaces, so in this case it shouldn't be required on the SFSB implementation class. We happen to support its use for both EJB2.x Remote and EJB3 Business Remote, but for a valid EJB2.x view the interface must extend EJBObject.
