Release note review, JDK-8210070, Release Note: The "supported_groups" extension should not present in the ServerHellos handshake message

[Xuelei Fan]

Hi,

Please review this release note:
    https://bugs.openjdk.java.net/browse/JDK-8210070

Per the "supported_groups" extension specification, the supported_groups 
extension should not present in the ServerHello handshake message. JDK 
11 cannot work with TLS servers that wrap the extension in ServerHello 
handshake messages.

We fixed the issue in JDK-8209965.  We may backport this update in a 
future update.

Thanks,
Xuelei
