Resolution

Enable Java Cryptography Extension (JCE) by:

1) Java 1.8.0_151 or later: 

In <jdk>/jre/lib/security/java.security uncomment:

#crypto.policy=unlimited

so it looks like:

crypto.policy=unlimited

or

2) Java version earlier than  1.8.0_151, by installing the correct JCE patch for your java version
