Description

If no renderer servlet is found in the DefaultGetServlet, it calls sendError(). If this is an included request, sendError usually fails as the response is already committed. In this case it's hard to detect the underlying problem.
Therefore I suggest to check if this is an included request and in this case throw a ServletException
I'm not in favour of checking for response isCommitted as this is more unpredictable
