What @user2936091 said is true but it doesn't solve the problem. I also had the exact same problem like you.

The solution is to remove fetch=FetchType.EAGER from the parent class. Wen fetch type EAGER is used, the instance of board in the post object will have the

 private List posts = new ArrayList();

populated because it was eagerly loaded, which means it still has a reference to itself, like @user2936091 mentions.

My workaround to still load related properties eagerly was to create a DBService class and load the objects from there like this

@Service
public class DBService {

    BoardRepository boardRepo;

    @Transactional
    public Board getBoardProcess(Long id) {
       Board board = boardRepo.findById(id).get();
       board.getPosts().size(); // This will trigger the db query so that posts gets loaded
       // It needs to be done within a transactional so that the session is still the same to populate the fields. If it's done from outside of this method. It will not work
    }
}
