>             Project: Hibernate ORM
>          Issue Type: Bug
>    Affects Versions: 4.1.0
>         Environment: Hibernate 4.1.0

> I have a simple class hierarchy that is mapped as joined subclass
> class Principal
> {
>   String uid;
> }
> class User extends Princpal
> {
> }
> class Group extends Princpal
> {
> }
> Till 4.0 it was possible to retrieve a user the natural ID using a criteria query for User.class and using uid as natural ID. In 4.1 this fails because Hibernate complains that column user_.uid doesn't exist. I can can still retrieve the user by using a criteria query for Principal.class. 
> So this works
> Criteria loCriteria = loSession.createCriteria(Principal.class);
> loCriteria.add(Restrictions.naturalId().set("uid", aUID));
> and this no longer works
> Criteria loCriteria = loSession.createCriteria(User.class);
> loCriteria.add(Restrictions.naturalId().set("uid", aUID));
> Hibernate knows the correct name of the column from the mapping file but in the end it looks for it in the wrong table
