------------------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HHH-4975
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4975
             Project: Hibernate Core
          Issue Type: Bug
          Components: annotations
    Affects Versions: 3.3.2
         Environment: Hibernate version 3.3.2.GA, HSQLDB 1.8.0.10
            Reporter: Christian Fritschi
            Priority: Critical
         Attachments: startTestDb.rar, ukMapping.rar, UkMappingTest.java

Level 1 (superClass)
-------
@MappedSuperclass
public abstract class AbstractMasterUk ...
    @Id
    private int id;
    ....
    @Column(name="MASTER_ID", nullable = false, length=50)
    private String masterId;

Level 2 (superClass)
-------
@Entity
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
@Table(name="MASTER_UK")
@DiscriminatorColumn(name="DOMAIN", discriminatorType=DiscriminatorType.STRING)
public class MasterUkBase extends AbstractMasterUk ....

Parent-Class
------------
@Entity
@org.hibernate.annotations.Entity(mutable = false)
@DiscriminatorValue(MasterUk1.DOMAIN)
public class MasterUk1 extends MasterUkBase ...

Child-Class
-----------
@Entity
@Table(name="DETAIL_UK")
public class DetailUk implements Serializable {
    @Id
    private int id;
    
    @ManyToOne(optional=false)
    @JoinColumn(name="MASTER", nullable=true, referencedColumnName="MASTER_ID")
    private MasterUk1 master;

Result:
org.hibernate.AnnotationException: referencedColumnNames(MASTER_ID) of annotations.playground.delta.ukMapping.DetailUk.master referencing annotations.playground.delta.ukMapping.MasterUk1 not mapped to a single property
