Auditor issue after upgrading to OpenJPA 2.3.0

After upgrading from OpenJPA 2.2.2 to 2.3.0, one of my regression tests fails since Auditor.audit() delivers too many objects. In particular, after changing a given field from x to y, some of the updated objects occur twice, with the surplus occurrence reporting the field as changed from y to y. I
