Description Gordon Yorke CLA 2012-03-20 11:03:51 EDT 
Through JSR 338 the JPA specification will add support for "treating" a joined attribute as a subclass of the attribute type for the purpose of defining a Query expression.

Support in both JPQL and Criteria API is required.
Comment 1 Gordon Yorke CLA 2012-03-20 11:03:58 EDT 
The Specification should be reviewed for requirements but a key point is this function is a join to the subclass table and any superclass results are eliminated from the result

Checked into main and 2.5.1
Comment 6 Chris Delahunt CLA 2013-06-17 09:59:34 EDT 
Fix checked in supports joined and single table inheritance.  Table per class is not supported and will result in exceptions stating the cast class does not use inheritance - this is due to Table per class support using an interface policy instead of an inheritance policy
