Description

While running the latest myfaces2 source code with a test JSP page, I've encountered the following error.
java.lang.ClassCastException: org.apache.myfaces.context.servlet.ResponseSwitch cannot be cast to javax.servlet.http.HttpServletResponse
at org.apache.myfaces.application.jsp.JspViewHandlerImpl.buildView(JspViewHandlerImpl.java:487)
at org.apache.myfaces.application.jsp.JspViewHandlerImpl.renderView(JspViewHandlerImpl.java:343)

etc......

As far as I can see, this is a bug, since there is an explicit cast to HttpServletResponse and the given parameter is of type ResponseSwitch, which is not a HttpServletResponse.

It looks like a recent change...
