Java 11 RC build - HTTPS handshake failure against a previously working server

As noted in that exception message, it appears that the server is
sending a "supported_groups" extension in its ServerHello message
(TLSv1.2). Reading about it, this seems to be a common issue with
certain servers and certain SSL implementations have added support to be
lenient with such servers https://github.com/openssl/openssl/pull/4463/files
