> When a mapped superclass (MSC) defines @Id fields, it appears that entities extending
the MSC use the MSC's type in the generated ObjectID's type field.  This can result in unexpected
primary key collissions between entities that are not intended to be related in an entity
inheritance hierarchy.  Attached to the JIRA is a junit test case that demonstrates the problem.
