Subject [jira] Created: (OPENJPA-89) Bulk delete fails to delete owned many-to-many relationship (entry remains in join table)

Bulk delete fails to delete owned many-to-many relationship (entry remains in join table)
-----------------------------------------------------------------------------------------

                 Key: OPENJPA-89
                 URL: http://issues.apache.org/jira/browse/OPENJPA-89
             Project: OpenJPA
          Issue Type: Bug
          Components: kernel
         Environment: Using Apache Derby (10.2.1.6)
            Reporter: David Ezzio


When executing the statement 

em.createQuery("delete from Subject").executeUpdate();

where Subject is in a many-to-many relationship with Book, and Subject owns the relationship,
one expects that the corresponding entry in the SUBJECT_BOOK table would be deleted.  This
happens when bulk deleting one-to-many relationships that are mapped with a join table, as
well as for *-to-one relationships mapped with a foreign key.  It also happens when individually
deleting objects.  However, it does not happen when bulk deleting the owning side of a many-to-many
relationship.
