Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 6.

Sun JDK and JRE come with limitation to respect US cryptography policy. Trying to
use long key will result in errors like "java.security.InvalidKeyException: Invalid
key length".

This package installs jars provided by Sun to get rid of those limitation.

# Priority is set to 1699 as we want to stay over default jce priority. It's actually 1617, I guess it'll stay 16XX to follow version number
