Self signed Java applet is not compatible with Java 7 Update 60

[rangler2]

I get the error "Your security settings have blocked a self-signed application from running".

https://www.java.com/en/download/help/java_blocked.xml

Supposedly an issue since Java 7 Update 51.

Sounds like it is possible to create the .jar in a different way to fix this?

Thanks
