What should root.getJoins return after a root.get("x")? #169
Description
I just found out that the following leads to different results in EclipseLink and Hibernate. And I can't decide from looking at the Spec which is the correct behavior:
CriteriaBuilder builder = em.getCriteriaBuilder();
CriteriaQuery<User> query = builder.createQuery(User.class);
Root<User> root = query.from(User.class);
root.get("manager");
// this returns 1 in EclipseLink and 0 in Hibernate.
root.getJoins()User is an entity with manager being a self-reference (I don't think the "self" part is relevant here).
@Entity
public class User {
@Id @GeneratedValue(strategy = GenerationType.AUTO) private Integer id;
@ManyToOne private User manager;
// getters and setters omitted for brevity.
}Please clarify in the specification and in the TCK which one it should be.
