--------------------------------------------------------------
I have a entity with an optional unidirectional one-to-one relationship.

@Entity
@IdClass( value = MbiMsgpa.PK.class )
@Table( name = "mbi_msgpa" )
public class MbiMsgpa implements Serializable, Comparable<MbiMsgpa>
...
/** Relation with MbiMsgpt. */
    @OneToOne( cascade = { CascadeType.PERSIST, CascadeType.REMOVE }, fetch = FetchType.LAZY )
    @Cascade( value = org.hibernate.annotations.CascadeType.DELETE_ORPHAN )
    @NotFound( action = NotFoundAction.IGNORE )
    @PrimaryKeyJoinColumns( {
        @PrimaryKeyJoinColumn( name = "msghd_serial", referencedColumnName = "msghd_serial" ),
        @PrimaryKeyJoinColumn( name = "part_no", referencedColumnName = "part_no" )
    } )
    private MbiMsgpt mbiMsgpt;
...
}

This worked using JBoss-4.2.4, but migrating to JBoss-6.0.0.

But using JBoss6 I get an exception like this:
