GitHub user gaohoward opened a pull request:

    ARTEMIS-1058 Jars in web tmp dir locked on Windows

    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.
