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
Attachments: jpa-test-joined.zip
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.
