title: OneToMany does not return values saved from other entity
body: <p>I have entity structure:</p>
  
  <pre><code>@Entity
  @Table(name = "users")
  public class User {
  
      @Id
      @GeneratedValue(strategy = GenerationType.IDENTITY)
      @Column(name = "id", updatable = false, nullable = false)
      private Long id;
  
      @OneToMany(fetch = FetchType.LAZY, mappedBy = "user", cascade = { CascadeType.ALL })
      List&lt;UserAgreement&gt; userAgreements= new ArrayList&lt;&gt;();
  
  }
  
  @Entity
  @Table(name = "user_agreements")
  public class UserAgreement {
  
      @Id
      @GeneratedValue(strategy = GenerationType.IDENTITY)
      @Column(name = "id", updatable = false, nullable = false)
      private Long id;
  
      @ManyToOne(cascade = CascadeType.REFRESH)
      @JoinColumn(name = "user_id")
      private User user;
  
      @ManyToOne(cascade = CascadeType.REFRESH)
      @JoinColumn(name = "agreement_id")
      private Agreement agreement;
  }
  
  
  @Entity
  @Table(name = "agreements")
  public class Agreement {
  
      @Id
      @GeneratedValue(strategy = GenerationType.IDENTITY)
      @Column(name = "id", updatable = false, nullable = false)
      private Long id;
  
      @OneToMany(fetch = FetchType.LAZY, mappedBy = "agreement", cascade = { CascadeType.ALL })
      List&lt;UserAgreement&gt; userAgreements = new ArrayList&lt;&gt;();
  }
  </code></pre>
  
  <p>I am using Spring Boot with JpaRepository. When I use <code>AgreementRepository extends JpaRepository&lt;Agreement, Long&gt;</code> to save Agreement and related UserAgreement, it works well and cascades necessary fields to DB:</p>
  
  <pre><code>agreement.getUserAgreements().add(new UserAgreement(user, agreement, status));
  agreementRepository.save(agreement);
  </code></pre>
  
  <p>However, after save, if try to retrieve <code>user.getActiveUserAgreements()</code>, I get empty list. It does not refresh. </p>
  
  <p>How to force User entity to get <code>List&lt;UserAgreement&gt;</code> which was saved from other side?</p>
