Hibernate @ Embedded in @Embeddable ignore annotation?

I'm trying to use @Embeddable

internally annother @Embeddable

which is supported as per spec, however, it looks like the JPA annotation in the class Code

below is being ignored. Enumeration (de) is converted in ordinal order instead of string representation. I can think of a few workarounds, but that's not a problem. I am trying to figure out what I am doing wrong.

I am using hibernate 4.2.5 with Spring 3.2.4

@Entity
public class ExampleEntity implements Serializable {

    @Id
    @GeneratedValue
    private Long id;

    @ElementCollection(fetch = EAGER)
    @CollectionTable(name="example_embeddable",
            joinColumns=@JoinColumn(name="example_entity_id"))
    private Set<ExampleEmbeddable> embeddables = new HashSet<>();

    // This enum is (de)serialized as a string just fine
    @Enumerated(EnumType.STRING)
    private AnotherEnum another;

    private String stuff;
}

@Embeddable
public class ExampleEmbeddable implements Serializable {

    @Embedded
    private Code code;

    // This enum is (de)serialized as a string just fine
    @Enumerated(EnumType.STRING)
    private StatusEnum status;
}

@Embeddable
public class Code implements Serializable {

    public enum Version {
        RED,
        BLUE,
        GREEN
    }

    private String code;

    //Why is this enum is (de)serialized by ordinal?
    @Enumerated(EnumType.STRING)
    private Version version;
}
