Hibernate et H2 "violation de contrainte d'intégrité Référentielle" pour OneToMany mise en correspondance bidirectionnelle

donc j'ai deux haricots simples -- FatKid et Hamburgers. Maintenant, pour des raisons que je ne connais pas, je dois pouvoir regarder non seulement tous les hamburgers que quelqu'un a mangés, mais aussi qui a mangé quel hamburger en particulier. Sur le code!

FatKid.java

import java.util.List;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToMany;
import javax.persistence.Table;

@Table
@Entity
public class FatKid {

    private int id;
    private String name;
    private List<Hamburger> hamburgers;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "FATKID_ID")
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }

    @Column
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

    @OneToMany(cascade = CascadeType.ALL)
    @JoinColumn(name="HAMBURGER_ID")
    public List<Hamburger> getHamburgers() {
        return hamburgers;
    }
    public void setHamburgers(List<Hamburger> hamburgers) {
        this.hamburgers = hamburgers;
    }

}

Hamburger.java

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

@Table
@Entity
public class Hamburger {

    private int id;
    private String description;
    private FatKid whoDoneAteMe;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "HAMBURGER_ID")
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }

    @Column
    public String getDescription() {
        return description;
    }
    public void setDescription(String description) {
        this.description = description;
    }

    @ManyToOne(cascade = CascadeType.ALL)
    @JoinColumn(name="FATKID_ID")
    public FatKid getWhoDoneAteMe() {
        return whoDoneAteMe;
    }
    public void setWhoDoneAteMe(FatKid whoDoneAteMe) {
        this.whoDoneAteMe = whoDoneAteMe;
    }

}

            // Create the SessionFactory from hibernate.cfg.xml
            return new Configuration().configure().buildSessionFactory();
        }
        catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            throw new ExceptionInInitializerError(ex);
        }
    }

}

donc quand j'exécute le code je finis avec la sortie (et tronquée de la trace de la pile)

Hibernate: insert into FatKid (FATKID_ID, name) values (null, ?)
Hibernate: insert into Hamburger (HAMBURGER_ID, description, FATKID_ID) values (null, ?, ?)
Hibernate: insert into Hamburger (HAMBURGER_ID, description, FATKID_ID) values (null, ?, ?)
Exception in thread "main" org.hibernate.exception.ConstraintViolationException: could not insert: [Hamburger]
        ...
Caused by: org.h2.jdbc.JdbcSQLException: Referential integrity constraint violation: "FK43797FE95067143: PUBLIC.HAMBURGER FOREIGN KEY(HAMBURGER_ID) REFERENCES PUBLIC.FATKID(FATKID_ID)"; SQL statement:
insert into Hamburger (HAMBURGER_ID, description, FATKID_ID) values (null, ?, ?) [23506-160]
        ...

ainsi le premier Hamburger est sauvé mais il explose ensuite sur le second. Tous les deux devraient pouvoir utiliser L'id du FatKid comme leur clé étrangère mais cela ne semble pas fonctionner. Toute suggestion serait grandement appréciée.

Merci, Kevin
