> SlingSafeMethodsServlet.service(ServletRequest req, ServletResponse res)
> tries to cast request & response objects to Sling's specific request &
> response interfaces. Therefore it catches a ClassCastException for those
> (seldom) cases where the servlet is erroneously used in a non-Sling
> environment and throws a ServletException in that case with the message "Not
> a Sling HTTP request/response".
> But this also swallows class-cast exceptions thrown inside custom servlets
> that inherit from SlingSafeMethodsServlet. The stacktrace is lost and the
> error message is wrong in this case.
> This can be fixed by doing an instanceof check instead of the try/catch block.
