Hilarious.

InetAddress.getByName("localhost").getCanonicalHostName() return 127.0.0.1 with JDK8 and localhost with JDK11. I would say JDK8 behaviour is wrong, but then, I have no idea what the expected behavior in the context of Spenego is.

I'm wondering whether testing against different JDKs is worth the effort here. Or in general...
