Running Jar with Unknown Publisher Blocked in Future Java Release

Hey all,

I’m looking at this page: http://www.java.com/en/download/help/appsecuritydialogs.xml#selfsigned

Particularly, the bit about self-signed jars (which gives the jar an UNKNOWN publisher) being blocked in a future release of Java.

When that comes to pass, what does that mean for Joe Developer, who wants to deploy his Java game or application as an applet or webstart?

I assume that a lot of games here will be affected, as libGDX, LWJGL, JMonkeyEngine, Slick2D, etc. all need to be signed. Is there an affordable way to obtain a certificate? Is there a better way to deploy our games? Is there a way around this fiasco? Am I overreacting, or is this a very very bad thing for the average hobbyist Java developer?
