I'm still having this problem - even with the generics refactored out of
the code.
I think there might be a problem with having the @Id on the
@MappedSuperclass. If I have everything in just one object everything is
okay. I'll see about creating some freestanding code where this happens -
but if someone can glean a solution from the code below that would be
appreciated.

Class hierarchy:
1. Interface top of the object graph:
public interface IDataBean<DATABEAN extends IDataBean<DATABEAN>> {
2. Second layer:
@MappedSuperclass
public abstract class DataBean<DATABEAN extends DataBean<DATABEAN>>
implements IDataBean<DATABEAN> {
@Id
public Long id = null;
3. Third layer
@MappedSuperclass
public abstract class AbstractDataBean<DATABEAN extends
AbstractDataBean<DATABEAN>>
extends DataBean<DATABEAN> {
4. Concrete
@Entity
public class TestDataBean extends AbstractDataBean<TestDataBean> {
