      Description

      JMXJsonServlet.doGet() has the following check:

            if (!HttpServer2.isInstrumentationAccessAllowed(getServletContext(),
                                                           request, response)) {
      

      Loading the class HttpServer2 triggers loading Jetty specific classes:

      SEVERE: Servlet.service() for servlet jmx-servlet threw exception
