K8s v1.30 seems to have something that stops our SSL Auth from working - causing SSL Handshake issues.
Seen in #455
If we run the tests with newer JDKs than the Java 8 ones used in our K8s Integration tests, the SSL Handshake issues go away. So it seems like Java 8 may not necessarily support the cipher suites that we need. The integration tests don't pass but they fail with other SSL issues associated with incomplete SSL setup (no client keystore, for one).
