> If there is Inheritance structure like:
> @Entity                                     (No entity annotation)              @Entity
> public class Party  extends public abstract Timelimited extends public abstract Versioned
> String name                                 Long timelimitedId                  Long versionedId                  
> Date date
> Long partyId
> the model generator generates Party_ with only name date and partyid (no extends )
> then it generates Timelimited_ with timelimitedId , but also without any parents (no extends)                 
> and lastly a Versioned_  is generated with versionedId                  
> Now I would like to say Party_.versionedId , but i cant
> A workaround is to annotate the Timelimited class (which is in the middle of the hierarchy) with a @Entity
> then the Party_ extends Timelimited which extends Versioned and everything works as desired
> but JPA allows  to have non entity classes in the middle of a hierarchy :
> Both abstract and concrete classes can be entities. Both abstract and concrete classes can be annotated with the Entity annotation, mapped as entities, and queried for as entities.
> Entities can extend non-entity classes and non-entity classes can extend entity classes:
