Unless she's talking about an internal prototype that never saw a public repository, Kris is wrong. The original prototype that saw a public repo was written by Joe and Craig in Python (mostly Craig IIRC) and lasted for all of about a week before they switched to Go. The original crew of contributors, all from Google, came from a Java background and definitely wrote Java-flavored Go, but no version of Kubernetes was ever written in Java.
