Hibernate JPA Embeddeble是否可能包含Embeddeble或Embeddeble集合？

我想知道是否有可能在另一个可嵌入元素中包含一个可嵌入元素集合

以下是我的供应商实体的一个示例，它有一个地址列表，属于可嵌入类型：

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

    private String supplierName;

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

---

我目前正在用JPA2+Hibernate3.6.x进行测试

在地址内使用可嵌入电话会导致我的测试出错。 下面是最底层的部分调试消息：
