            em.persist(teamB);

            Member member1 = new Member();
            member1.setUsername("member1");
            member1.setTeam(teamA);
            em.persist(member1);

            Member member2 = new Member();
            member2.setUsername("member2");
            member2.setTeam(teamA);
            em.persist(member2);

            Member member3 = new Member();
            member3.setUsername("member3");
            member3.setTeam(teamB);
            em.persist(member3);

            em.flush();
            em.clear();

            List<Member> result = em.createQuery("select m from Member AS m join m.team", Member.class)
                    .getResultList();

            for (Member member : result) {
                System.out.println("member = " + member);
                System.out.println("member.getTeam().getClass() = " + member.getTeam().getClass());
            }

<아래는 Console 결과입니다>

member = Member{id=3, username='member1'}

member.getTeam().getClass() = class hellojpa.Team$HibernateProxy$OSndAo5E

member = Member{id=4, username='member2'}

member.getTeam().getClass() = class hellojpa.Team$HibernateProxy$OSndAo5E

member = Member{id=5, username='member3'}

member.getTeam().getClass() = class hellojpa.Team$HibernateProxy$OSndAo5E

모두 같은 프록시 객체가 나오는 것 같습니다.

member3은 1,2와 다른 팀인데, 왜 같은 프록시 객체가 나오나요?
