I'm trying to get the PluralAttributePath from a collection that is defined in a MappedSuperclass

@Entity
public class Person extends PersonBase {
...
}

@MappedSuperclass
public abstract class PersonBase {

@OneToMany()
private Set<Address> addresses = new HashSet<Address>();
public Set<Address> getAddresses() { return addresses; }
public void setAddresses(Set<Address> addresses) { this.addresses = addresses; }
}

Executing the following

criteriaQuery = criteriaBuilder.createQuery(Person.class);
root = criteriaQuery.from(Person.class);
Path<?> pathAddresses = root.get("addresses");

throws the exception

org.hibernate.MappingException: Unknown collection role: testcase.hibernate.PersonBase.addresses
at org.hibernate.impl.SessionFactoryImpl.getCollectionPersister(SessionFactoryImpl.java:701)
at org.hibernate.ejb.criteria.path.PluralAttributePath.resolvePersister(PluralAttributePath.java:58)

If you move the collection from the MappedSuperclass to the Entity everything works fine.

This is a very simple example and should work (it is working with other jpa providers).
Therefore I added an issue to the bug tracker in February together with a test case.
But I got no reaction.

Am I doing something wrong or is this a bug?
Hopefully someone can help me.
