> Multiple test cases attempt to bulk delete instances of Person. However, the Employee
subclass of Person might wind up having a non-nullable foreign key reference to Insurance
or another Employee (via the "mentor" field). While the defaut Derby TCK schema does not have
this constraint, in order to be flexible for other databases that will enforce the foreign
key by default, some effort should be made to ensure that there are no relation constraints
before the bulk deletes are attempted. This can be done by adding a nullForeignKeyReferences()
method that will manually make sure that the relations are nulled. See the attached patch.
