使用install4j创建的exe在启动30-40秒后会占用所有CPU

I have created an installer for my Java application using install4j. it is running on JDK1.6 and uses Jetty as a web server and struts2 as an MVC. The application installs just fine and an exe file is created correctly. When I launch the application by double clicking on the exe file, the application launch and starts just fine and all functionality behaves correctly. After about 30 to 40 seconds from launching the application, I notice that the exe process is eating almost all the CPU power (up to 99%). making it so hard to use any other application on my PC. This only happens on Windows XP and Vista. But when I try it on Windows 7 I do not get this problem. The windows XP and Vista machines spec are very good (3GHZ processor with 4 GB of RAM).I have created an installer for my Java applica
