title: Struts2 upgrade (2.0.11 to 2.3.4), issues with GWT
body: <p>I've been tasked with upgrading an application from Struts2 v2.0.11 to v2.3.4 due to a vulnerability.  I've successfully managed to handle the conflicts and upgrading of all the dependencies with the exception of what I think is GWT.  The version of GWT is currently sitting at 2.0.3.</p>
  
  <p>My main issue is a 404 for something called '/apps/dispatch', which is referenced by:</p>
  
  <pre><code>serve("/apps/dispatch").with(StandardDispatchServiceServlet.class);
  </code></pre>
  
  <p>No compile issues, no runtime issues (other than the 404).</p>
  
  <p>Without upgrading the Struts2 version the app runs as expected.  Any thoughts on why the Struts2 upgrade breaks the GWT functionality?</p>
