Entities support class inheritance, polymorphic associations, and polymorphic queries. Entity classes can extend non-entity classes, and non-entity classes can extend entity classes. Entity classes can be both abstract and concrete.The roster example application demonstrates entity inheritance, as described...
Class.getMethod and Class.getMethods were not updated with the 8 release to match the new inheritance definition (both may return non-inherited superinterface methods). Typically, the distinction is of no consequence; and for compatibility, it is preferred that the identity and number of returned...
