I just found this on the Oracle site;

"Changes to Java Control Panel's Security Settings

In this release, low and custom settings are removed from the Java 
Control Panel(JCP)'s Security Slider.

Depending on the security level set in the Java Control Panel and the 
user's version of the JRE, self-signed or unsigned applications might 
not be allowed to run. The default setting of High permits all but local 
applets to run on a secure JRE. If the user is running an insecure JRE, 
only applications that are signed with a certificate issued by a 
recognized certificate authority are allowed to run."

What do they mean by a secure JRE?
