My project is currently working with Eclipselink v1.1.3 and I am attempting to upgrade to Eclipselink 2.0.1. During deletes I am running into trouble with a foreign key constraint violation on an object that has a many-to-many mapping. The problem is that the intermediate table is not being deleted.

Have there been any changes since 1.1.3 that would cause the intermediate record to not be deleted?

My problem is not as simple as I had thought as I cannot reproduce it on it's own. As a simple unit test it is working as advertised.

The problem was indeed more involved than I originally thought. Many to many mappings do indeed have an issue with deleting the intermediate join table record when the mapping is inherited from another descriptor.

More information can be found in bug #303514 including a patch that fixes the problem.
