Ist es möglich, für einen PPV embeddable enthalten Embeddable oder Sammlung von Embeddables?

Frage ich mich, ob es möglich ist, eine ElementCollection von Integrierbaren in eine andere Einbettbare ?

Hier ein Beispiel von meinem Lieferanten Entität, die hat eine Liste von Adressen, die von einem eingebauten Typ :

@Entity
public class Supplier extends BaseCommonEntity {
    @Column(unique=true)
    private String supplierCode;    

    private String supplierName;

    @ElementCollection
    private List<Address> addresses;
....

---

Und hier ist mein embeddable-Adresse, enthält eine Liste der integrierbaren Telefon

@Embeddable
public class Address {
    private String address;
    private String city;
    private String country;
    private String postcode;

    @ElementCollection
    private List<Phone> phones;
    public List<Phone> getPhones() {
        return phones;
    }

    public void setPhones(List<Phone> phones) {
        this.phones = phones;
    }
...

---

Und hier ist die integrierbaren Telefon-definition

@Embeddable
public class Phone {
    private Long phoneCountryCode;
    private Long phoneCityCode;
    private Long phoneNo;
    private Long faxCountryCode;
    private Long faxCityCode;
    private Long faxNo;
...

Im derzeit testet diese mit JPA 2 + Hibernate 3.6.x

Verwendung des einbettbaren Handy drin die Adresse führt zu Fehler in meinem test.
Hier ist die teilweise debug-Meldungen aus, die die meisten unten :

Ohne dieses Teil löst das problem

    /**** REMOVE ALL OF THIS FROM THE CODE TO SOLVE THE PROBLEM ****/
    @ElementCollection
    private List<Phone> phones;
    public List<Phone> getPhones() {
        return phones;
    }

    public void setPhones(List<Phone> phones) {
        this.phones = phones;
    }
