NoSuchElementException in AnnotationBinder.makeInheritanceJoinColumns() when Joined subclass mixed with @MapsId foreign-key id
------------------------------------------------------------------------------------------------------------------------------

                 Key: HHH-7135
                 URL: https://hibernate.onjira.com/browse/HHH-7135
             Project: Hibernate ORM
          Issue Type: Bug
          Components: core
    Affects Versions: 4.1.0
         Environment: Hibernate 4.1.0.Release, any database
            Reporter: Didier Villevalois

When you have a joined class hierarchy and the root class is has a foreign-key id, makeInheritanceJoinColumns fails.

@Entity(name = "org.clinigrid.jpa.test.joined.AThing")
@Inheritance(strategy = InheritanceType.JOINED)
public abstract class AThing {

	public AThing() {
	}

	public AThing(ThingHolder holder) {
		this.holder = holder;
	}

	@Id
//	@GeneratedValue(generator = "foreign")
//	@GenericGenerator(name = "foreign", strategy = "foreign", parameters = { @Parameter(name = "property", value = "holder") })
	private Integer id;

	@MapsId
	@OneToOne(mappedBy = "thing")
	private ThingHolder holder;

	public Integer getId() {
		return id;
	}

	public ThingHolder getHolder() {
		return holder;
	}
}

Commenting the @MapsId and un-commenting the @GeneratedValue and @GenericGenerator fixes the problem.
I was not able to find the root of the problem in hibernate's code.

Attached is a test maven project.
