This is because you do not have unlimited strength jurisdiction policy files installed.

Install one of the following:

Java 6 Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files Java 7 Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files Java 8 Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files

Extract them to: ${java.home}/jre/lib/security/
