Cache causing problems!

Hi guys,

I'm using Java Web Start to distribute a client updater for a RuneScape Classic private server, which then updates the client. It generally works fine, but randomly for times you get the "Unable to launch application." error which always proves to be a cache problem. If they clear their cache it works fine again.

Now, I've made a .BAT for them to use which simply launches it using this:

It works every time flawlessly...

So what exactly is the difference in using this:

Can someone please help? I'm forced to ask users to save the .BAT to their desktop otherwise it messes up a few launches later.
