title: HTTP status code 500 for NotFoundException
body: <p>I'm developing an application with RESTEasy and JBOSS 5.1.</p>
  
  <p>For specific situations, I have to return 404 error (not found).</p>
  
  <p>In the sources, I'm using </p>
  
  <pre><code>import org.jboss.resteasy.spi.NotFoundException;
  throw new NotFoundException(...);
  </code></pre>
  
  <p>The problem is that, in the header response, I have 
  Status Code: 500 internal server error</p>
  
  <p>even if in the body the exception is:</p>
  
  <pre><code>org.jboss.resteasy.spi.UnhandledException: org.jboss.resteasy.spi.NotFoundException
  </code></pre>
  
  <p>This is a normal behavior? It's not possible to return Status Code: 404?</p>
