    Description

      http://markmail.org/message/urk6a4c2owilyxmw

      If a class for an abstract entity is defined as "abstract" (for now manually, see CAY-1411), and a callback method is not defined (it will be generated as abstract in _Entity class), Cayenne would throw something like this:

      Exception in thread "main" java.lang.IllegalArgumentException: Class mrg.model.Product has no valid callback method 'xxxxx'

      inside CallbackOnEntity. CallbackOnEntity should take into account abstract method definition in a superclass to prevent this from happenning.

      For now a simple workaround is to define a noop non-abstract method in the abstract subclass.
