Description Shahim Essaid CLA 2012-05-23 19:25:06 EDT 
Build Identifier: 2.3.2 release and 2.4.0 milestone M19

When a super entity is annotated with @JoinTable and sub entities do not have association overrides, the generated DDL for table per class is incorrect. 

EclipseLink maps all the sub entities to the same join table of the parent entity.

Seems we are generating constraints, but should not be for table per class inheritance as can have multiple target tables.
Comment 3 James Sutherland CLA 2013-07-09 14:14:16 EDT 
fixed, no longer generate foreign key constraints for table_per_class
