Error description

  • Error Message: The Webstart Application jars use to get
    downloaded from server instead of using cache for every launch
    of the application even though the Application jars have being
    not modified.
    .
    Stack Trace: N/A
    .
    For a Webstart Application, if user specify
    -Djava.protocol.handler.pkgs=sun.net.www.protocol" command line
    property, Webstart use to ignore the Cache and download the
    application jars every time from server to launch the
    application. This incorrect behaviour of Webstart can be
    detected by the usage of network traffic monitor tools like
    WireShark during a Java Web Start application launch.
