title: Method findTopBy (JPA) returns differents objects
body: <p>I am new to Java and I have a question:</p>
  <p>I have a method in <em>MessageRepo</em>:</p>
  <pre><code>Message findTopByOwnerOrderById(User user);
  </code></pre>
  <p>And every time it returns a different Message, although it should only return the <strong>first</strong> from <strong>sorted</strong> data. What am I doing wrong?</p>
