> Exploring code I found that Tomcat`s implementation of RequestDispatcher expects that passed Response/Request objects is original objects or is wrapped by ServletRequestWrapper/ServletResponseWrapper. But geronimo-servlet_2.5_spec/HttpServlet.java#doHead() use NoBodyResponse class which is not instance of  ServletResponseWrapper. So, exception thrown.
