Authentication Failures When Running on Java 8u60+
A change in the Java 8 JVM broke some of the toString()
string generation
of Joda Time 2.8.0, which stopped the Amazon S3 client from being able to generate
authentication headers suitable for validation by S3.
Solution: Make sure that the version of Joda Time is 2.8.1 or later, or use a new version of Java 8.
