Pinaki Poddar commented on OPENJPA-677:
---------------------------------------
This is an intermediate (and inaccurate) fix for the problem.
This will only work when the most-derived class is target of a relation.
For example, declared type of RegularUser.admin is Admin which is the
most-derived class in this case and hence only the fix works. Otherwise, most
likely it will show the same error.
Will attempt to put a more comprehensive fix
> Single Table Inheritance Strategy causes entity identity issues
