Portlet Issue with I18Interceptor

    Details

      Description

      Portlets always throw the following exception:

      java.lang.IllegalStateException: Not allowed in a portlet

      Below is the method in the classs
      org.apache.struts2.portlet.servlet.PortletServletRequest where this always
      happens:

      public Cookie[] getCookies() {
          if (portletRequest instanceof HttpServletRequest) {
              return ((HttpServletRequest) portletRequest).getCookies();
          }
          throw new IllegalStateException("Not allowed in a portlet");
      }
      

      Apparently, the "portletRequest" variable is not an instance of "HttpServletRequest".

      NOTE - There are many other methods in class PortletServletRequest that use the exact same assumption/logic as the "getCookies()" method.

      That class is invoked by the class
      org.apache.struts2.interceptor.I18nInterceptor, which was just changed in version 2.5.5. See change https://issues.apache.org/jira/browse/WW-4686

      Finally, below is a partial stack trace
