Description Gordon Yorke CLA 2011-12-22 13:49:32 EST 
In JSR 338 the JPA specification will add support for specifying an "ON" clause within the JOIN clause of a JPQL statement.  This bug will be tracking the work needed to support this JPQL feature.

Much of the work has been completed through a related bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=312146

Design documentation can be found at http://wiki.eclipse.org/EclipseLink/DesignDocs/367452
Comment 2 Gordon Yorke CLA 2012-03-13 15:09:12 EDT 
The specification has also added APIs to the Criteria API support the ON clause.  Criteria API implementation should be part of this feature.
Comment 3 James Sutherland CLA 2012-04-11 10:46:32 EDT 
JPQL support added, Criteria API still required.

Comment 9 Gordon Yorke CLA 2012-12-17 14:48:16 EST 
Specification has been updated to disallow FETCH JOINs with ON clause and '.' joins within the ON clause.

Final update to the spec should be reviewed prior to making any updates.
Comment 10 Chris Delahunt CLA 2013-04-03 11:56:21 EDT 
No additional changes from the prior check in are required.
