WW-4722 Uses proper read method
> Portlet Issue with I18Interceptor
> ---------------------------------
>
> Key: WW-4722
> URL: https://issues.apache.org/jira/browse/WW-4722
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors, Plugin - Portlet
> Affects Versions: 2.5.5
> Reporter: Todd Kofford
> Assignee: Lukasz Lenart
> Labels: interceptors, portlet
> Fix For: 2.5.8
>
>
> Portlets always throw the following exception:
> {quote}
> java.lang.IllegalStateException: Not allowed in a portlet
> {quote}
> Below is the method in the classs
> *org.apache.struts2.portlet.servlet.PortletServletRequest* where this always
> happens:
> {code:java}
> public Cookie[] getCookies() {
> if (portletRequest instanceof HttpServletRequest) {
> return ((HttpServletRequest) portletRequest).getCookies();
> }
> throw new IllegalStateException("Not allowed in a portlet");
> }
> {code}
> 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]
