  </code></pre>
  
  <p>The call that's throwing the exception.    </p>
  
  <pre><code>Person copy = (Person) SerializationUtils.clone(PersonHolder.getPerson(request));
  </code></pre>
  
  <ul>
  <li><code>PersonHolder.getPerson(request)</code> DOES return a <code>Person</code></li>
  <li><code>Person</code> implements <code>Serializable</code></li>
  <li><code>request</code> is an HttpServletRequest which has data that is being passed to the method in which I try to clone the <code>Person</code>. It contains data that the <code>getPerson</code> method needs. I don't believe this has anything to do with my problem but I just wanted to be clear what it was doing.</li>
  <li>The <code>commons-lang-2.4.jar</code> is included in my project.</li>
  <li>I've imported <code>org.apache.commons.lang.SerializationUtils</code> and the <code>Person</code> class.</li>
  </ul>
  
  <p>Any ideas what I may be doing wrong here?</p>
