Java-applets in the internet are not used anymore as i explained. And if quite a few poeple use it in their intranets they don't care particular for a 0day. If their intranet is used to deploy these, everything is already lost.

Even if the webbrowser that displays the intranet applets is used to surf the internet it's not a attac surface as you have to whitelist every site that's able to use applets.
