launch from desktop shortcuts of java web start application will not pick up JNLP update from server

create a desktop shortcut for any java web start application

ensure you can launch application via the desktop shortcut

update the server JNLP file for the application. e.g change the application title.

launch from the shortcut again. it will never pick up the update to the JNLP file. the shortcut won't be updated to reflect the new title.

if you launch directly from browser JNLP link, it works and will pick up the update.

this has been reported externally as well, see last comment here:
