doesn't compile on JDK 11 (sun.security.util.HostnameChecker)

[ssl-config] [error] one error found

also reproducible outside dbuild with e.g sslConfigCore/compile. I expect you will also see the failure if you add openjdk11 to the matrix in .travis.yml

We should be able to remove HostnameChecker now that we're well past JDK 1.6
