JPA2.1 (WildFly8 に含まれる) の列挙型に問題があります。列挙型のセットを使用するクラスは次のとおりです。

@Entity
@Table(name = "ZOO")
public class Zoo extends BaseEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Access(AccessType.PROPERTY)
    private Long id;
    private String name;
    @ElementCollection(targetClass = String.class, fetch = FetchType.EAGER)
    @CollectionTable(name = "ZOO_ANIMALS", joinColumns
        = @JoinColumn(name = "ZOO_ID", referencedColumnName = "ID"))
    @Enumerated(EnumType.STRING)
    private Set<Animal> animals = new HashSet();
}

次に、動物を列挙します。

public enum Animal {
    PANDA,
    LION,
    ZEBRA,
    TIGER;
}

サーバーを起動しようとすると、次のエラーが表示されます。

これは Jboss 7.1.1.Final で問題なく動作しました。これにコンバーターを使用する必要がありますか ( http://somethoughtsonjava.blogspot.fi/2013/10/jpa-21-type-converter-better-way-to.html ) または何が問題になる可能性がありますか? すべての助けに感謝します！
