My findings are the same:
This prevents warnings with Java 7u21 – 7u40:
Manifest-Version: 1.0 Trusted-Library: true
This exclusivly prevents warnings with Java 7u45:
Manifest-Version: 1.0 Application-Library-Allowable-Codebase: * Caller-Allowable-Codebase: *
Mixing both won’t work in 7u45.
Did anyone find a way to allow SIGNED applets with “all-permissions” to run without warnings in both JRE-versions?
What the hell is wrong with oracle?
