リストであるフィールドで Restrictions.in を使用するにはどうすればよいですか?

これが私のモデルです：

@Entity
@Table(name = "W_GROUP", schema = "U_FRONTEND")
public class UserGroup {
@Id
@Column(name = "GROUP_ID")
private Long id;

@Column(name = "NAME", length = 100, nullable = false, unique = true)
private String name;

@ElementCollection(targetClass = Feature.class)
@JoinTable(name = "W_FEATURE", joinColumns = @JoinColumn(name = "GROUP_ID", nullable = false), schema = "U_FRONTEND")
@Column(name = "NAME", nullable = false, length = 50)
@Enumerated(EnumType.STRING)
private List<Feature> features;

@JoinTable(name = "W_USER_GROUP", joinColumns = @JoinColumn(name = "GROUP_ID"), inverseJoinColumns = @JoinColumn(name = "USER_ID"), schema = "U_FRONTEND")
@ManyToMany
private List<User> users;

@Column(name = "UPD_USER", nullable = false, length = 50)
private String updUser;

@Column(name = "UPD_DATE", nullable = false, columnDefinition = "date")
private Calendar updDate;
// Getters and setters
}

いくつかの機能を持つグループのみを取得しようとしています:

Criteria criteria = session.createCriteria(UserGroup.class);

            criteria.addOrder(new Sort(Order.ASC, "name").getOrder());

            criteria.add(Restrictions.not(Restrictions.in("features",
                    FeatureUtils.getInvalids())));

しかし、これはエラーを返します:

あまりきれいではないことはわかっていますが、ids ( List<Long> featureIds) のリストを作成してから、次のことを行うことができます。

Restrictions.in("features", featureIds);
