        public void start()

      • stop

        public void stop()
        Stops this classloader. this will "stop" the underlaying platform which means that
      • the connection pools are closed
      • all timer tasks stopped (if cronjob extension is installed)
      • the cache is cleared
      • all fields of static classes are nulled (due to GC problems)
