Unknown mappedBy using @Id @OneToOne
------------------------------------

                 Key: HHH-5495
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5495
             Project: Hibernate Core
          Issue Type: Bug
    Affects Versions: 3.6.0.Beta3, 3.5.0-Final
         Environment: Hibernate 3.5 and 3.6.0-Beta3
Glassfish v3.0.1
            Reporter: Alfio

This example should work according to JSR 317, Section 2.4.1.3, Example 4 Case(a):

@Entity
public class Person {

	@Id
	private String ssn;

	@Column( nullable = false )
	private String name;

	@Column( nullable = false )
	private String surname;
	
	@OneToOne( mappedBy = "person" )
	private PersonDetail personDetail;

	... getters and setters ...
}

@Entity
public class PersonDetail {

	@Id
	@OneToOne
	private Person person;

	@Column( nullable = true )
	private int age;

	@Column( nullable = true )
	private String city;

	... getters and setters ...
}

During deploy the following error is shown:

It works well if I use MapsId (following example 4 case b in JSR 317)

@Entity
public class PersonDetail {

	@Id
	private String ssnPK;

	@MapsId
	@OneToOne
	private Person person;
...
