Allow database to throw Referential Integrity violation.

SourceForge Submitter: vbnaik .
Currently Jboss nullifies the foreign key constraints
before deleting a referenced entity, and Referential
integrity violation is not thrown by database, when fk
constraints are defined at database level.

Say for example:

An EJB A is being referenced by EJB B (M:1 CMR). So on
deletion of EJB A we should get referential intergrity
violation from database as B is referencing A.

When we try to delete A invoking the remove() method,
JBOSS AS first nulls out the reference of A in ejb B and
then deletes it and as a result no referential integrity
error from database is thrown.

It is big pain to code in business logic for referential
integrity, we would highly appreciate, if an option is
provided in JBoss to turn off the this logic, if at all a
developer wants database to handle the referntial
integrity for the application.
