[hibernate-dev] Use @AssociationOverride with @MapKeyJoinColumn

[Vlad Mihalcea]

The JPA spec does not specify a way to override the MapKeyJoinColumn. You
can override the association, like the JoinColumn for a ManyToOne or a
JoinTable for OneToMany.

In your case, maybe it's better to move that association out of the
embeddable.
It's always a good idea to keep the model as simple as possible.
