title: Return String from Java to Ajax does not work correctly
body: <p>From Java I return a string to Ajax</p>
  
  <pre><code>return "ehy";
  </code></pre>
  
  <p>From Jquery:</p>
  
  <pre><code>$.ajax({
          type: 'GET',
          url: "getNote", 
      }).done(function(principal){
          alert(principal);
      }).error(function(xhr) {
          manageError(xhr); 
      });
  </code></pre>
  
  <blockquote>
    <p>alert says: ""ehy"";</p>
  </blockquote>
  
  <p>Why four apexes?</p>
  
  <p>I would <strong>ehy</strong>, instead the <strong>content</strong> of principal is <strong>"ehy"</strong>.</p>
