We need to implement workarounds for the two bugs:
6408620: Vista: Java Web Start JRE auto-download not working, and
6406802: Vista: "Update Now" button on Java Control Panel fails to run jucheck.exe
which are closed as duplicates of:
6410605: Vista: Runtime.exec does not handle exe files needing elevated privileges
We will change the runtime.exec in control panel to launch cmd.exe, and we will work around the auto-download problem for now by by sending out the os="windows-vista" so the curent servlet will respond that there are no versions available to auto-download.
