> Hibernate has long treated 'id' in a special manner in HQL and Criteria queries.  The drawback to this has always been that it effectively means users cannot define non-identifier properties named id and refer to those properties in HQL/Criteria queries.
> Thus, I will change this such that:
> (1) 'id' can still be used to refer to the identifier property, whatever the property's actual name, as long as the entity does not define a non-identitifer property named id.
> (2) if the entity defines a non-identifier property named 'id', using 'id' in HQL or Criteria queries will refer to this non-identifier property; users would need to refer to the identifier property by its actual name.
> FYI, the original reason for this feature was to support entity's which did not define an identifier property at all (users were responsible for managing the ids seperately.  That feature was never really recommended and has been deprecated since early in the 3.x development.
