@Index Columns in @MappedSuperClasses don't work
------------------------------------------------

                 Key: HCANN-34
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HCANN-34
             Project: Hibernate Commons Annotations
          Issue Type: Bug
    Affects Versions: 3.2.0
         Environment: hibernate-commons-annotations-3.2.0.jar
hibernate-core-3.6.0.jar
postgres
java 1.6
            Reporter: Mathias Reem


Indices in MappedSuperclass are not created in each child Entity, but only in one of them, as index names are global (at least in postgres), for the other Entites I get errors:

10:00:17 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate]: Unsuccessful: create index hash on B (hash)
10:00:17 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate]: ERROR: relation "hash" already exists


{code:title=Root.java|borderStyle=solid}
@MappedSuperclass
abstract class Root {
  @Column(nullable = false, unique = true)
  @Index(name = "hash")
  private String hash;
	
  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  private Long id;

  // Getter, Setter, ...
}
{code}

{code:title=A.java|borderStyle=solid}
@Entity
public class A extends Root {
  // Getter, Setter, ...
}
{code}

{code:title=B.java|borderStyle=solid}
@Entity
public class B extends Root {
  // Getter, Setter, ...
}
{code}
