> The embedded jetty web server's WebAppClassloader holds up webapp's jar files
> and does not release them after close. For that reason the web app's temp dir
> cannot be cleaned up on Windows. (Other platforms like Linux doesn't prevent
> a force delete of files even they are not released).
> As long as this behavior exists we need to have a workaround to let
> the tmp dir be cleaned up.
> It is possible that we use a 'customized' classloader to replace jetty's
> WebAppClassloader, in which we manually iterate every JarFile resources
> and close them.
