       Body:
Thank you very much for the patch, it works fine and is very useful!

However I have got a problem with it.

If Class A is an implementation of the interface MyInterface:
  session.createCriteria(MyInterface.class).list() works fine
  session.createCriteria(MyInterface.class).count() fails with :
    net.sf.hibernate.MappingException: Unknown entity class: MyInterface.cl=
ass
  session.createCriteria(A.class).count() works fine again

Is there something missing in the patch?

Another point, makes it sense that count() returns long, but setFirstResult=
(int)?

Again, thank you for count().
