>          Issue Type: Bug
>    Affects Versions: 3.0
>            Reporter: Andrus Adamchik

>             Fix For: 3.1M1, 3.0.2
> 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.
