Cannot fetch through @EmbeddedId field

Hibernate ORM
1

Hello, i have a problem with fetching through EmbeddedId field, here is the field:

@OneToMany(fetch = FetchType.LAZY, targetEntity = User_GameSession.class, mappedBy = "userGameSessionCK.gameSession")
    private List<User_GameSession> gameSession_users;

The related class:

@Table(name = "user_to_game_session")
@Entity
@EntityListeners(value = {UsersNumForGameSessionManager.class})
@Getter
@Setter
@NoArgsConstructor
public class User_GameSession {
    @EmbeddedId
    private User_GameSessionCK userGameSessionCK;

    public User_GameSession(User user, GameSession gameSession) {
        this.userGameSessionCK = new User_GameSessionCK();
        this.userGameSessionCK.setUser(user);
        this.userGameSessionCK.setGameSession(gameSession);
    }
}

The embeddable class:

@Getter
@Setter
@NoArgsConstructor
@Embeddable
public class User_GameSessionCK implements Serializable {
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "user_id")
    protected User user;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "game_session_id")
    protected GameSession gameSession;

    public User_GameSessionCK(User user, GameSession gameSession) {
        this.user = user;
        this.gameSession = gameSession;
    }
}

And fetching chain logic:

root.fetch("gameSession_users", JoinType.LEFT).fetch("userGameSessionCK", JoinType.LEFT).fetch("user", JoinType.LEFT)

It traps into infinite loop inside org.hibernate.metamodel.mapping.internal.ToOneAttributeMapping.createCircularBiDirectionalFetch method on 1259 line of code

...
while ( realFetchParent.getNavigablePath() != parentNavigablePath ) {
	realFetchParent = ( (Fetch) fetchParent ).getFetchParent();
}
...

Is it resolvable with using of EmbeddedId field or i have to use another mapping strategy?

Hibernate version: 6.6.11.Final

Hi @octobronze, this sounds like a bug. I would kindly ask you to try to create a reproducer with our test case template and if you are able to reproduce the issue, create a new ticket in our issue tracker and attach that reproducer.
