title: (1+N) selects with OnetoOne associations
body: <p>Considering the following model:</p>
  
  <pre><code>@Entity
  public class User {
  
      @Id
      @Column(name = "USER_ID")
      private Long userId;
  
      @Column(name = "FIRST_NAME")
      private String firstName;
  
      @Column(name = "LAST_NAME")
      private String lastName;
  
      @OneToOne
      @PrimaryKeyJoinColumn
      private UserExt userExt;
  ...     //getters and setters
  
  }
  
  @Entity
  public class UserExt {
  
      @Id
      @Column(name="USER_ID")
      private Long id;
  
      private String cdpId;
  
      private Date lastChanged;
  ...     //getters and setters
  }
  </code></pre>
  
  <p>when executing :</p>
  
  <pre><code>Query query = session.createQuery("from User");
  List&lt;User&gt; list = query.list();
  </code></pre>
  
  <p>Hibernate executes </p>
  
  <pre><code>Hibernate: select user0_.USER_ID as USER1_0_, user0_.FIRST_NAME as FIRST2_0_, user0_.LAST_NAME as LAST3_0_, user0_.EXT_USERNAME as EXT4_0_ from USER user0_
  Hibernate: select userext0_.USER_ID as USER1_1_0_, userext0_.cdpId as cdpId1_0_, userext0_.lastChanged as lastChan3_1_0_ from USER_EXT userext0_ where userext0_.USER_ID=?
  Hibernate: select userext0_.USER_ID as USER1_1_0_, userext0_.cdpId as cdpId1_0_, userext0_.lastChanged as lastChan3_1_0_ from USER_EXT userext0_ where userext0_.USER_ID=?
  ...
  ...
  </code></pre>
  
  <p>Using a query with specific properties works (select u.firstName, u.userExt.cdpId).</p>
  
  <p>However since I want the full User Entity ("from User"), hibernate generates one select for each result row in the first.</p>
  
  <p>I don't get it since the default fetch strategy should be LAZY not EAGER. Forcing it to LAZY didn't fix the problem.</p>
