Once this is done the CPU will jump dramatically. I have attached a NetBeans project that shows this phenomenon. When viewing the index.jsp file, just click the "End" button. It should be noted that CPU usage remains normal if the web application is first undeployed then deployed again. CPU usage will only spike if the web application is explicitly reloaded.
