SO_FLOW_SLA option is not supported for ServerSocket on any platform, but UnsupportedOperationException is not thrown if we try to set or get SO_FLOW_SLA option for ServerSocket on Solaris 11.2

To reproduce this problem please run next code on Solaris 11.2 or later host:

import jdk.net.ExtendedSocketOptions;
import jdk.net.Sockets;
import java.io.IOException;
import java.net.ServerSocket;

public class Test {

    public static void main(String[] args) throws IOException {
        boolean isOptionSupported = Sockets.supportedOptions(ServerSocket.class)
                .contains
                        (ExtendedSocketOptions.SO_FLOW_SLA);
        System.out.println("SO_FLOW_SLA supported: " + isOptionSupported);
        Sockets.getOption(new ServerSocket(), ExtendedSocketOptions
                .SO_FLOW_SLA);
    }
}

Expected: 
SO_FLOW_SLA supported: false
Exception in thread "main" java.lang.UnsupportedOperationException: SO_FLOW_SLA
        at jdk.net.Sockets.getOption(Sockets.java:262)
        at Test.main(Test.java:19)

Got:
SO_FLOW_SLA supported: false
Exception in thread "main" java.net.SocketException: set option SO_FLOW_SLA failed
        at sun.net.ExtendedOptionsImpl.getFlowOption(Native Method)
        at java.net.PlainSocketImpl.getOption(PlainSocketImpl.java:82)
        at java.net.ServerSocket.getOption(ServerSocket.java:980)
        at jdk.net.Sockets.getOption(Sockets.java:172)
        at Test.main(Test.java:19)

Cause:
jdk 8 implementation contains check for getOption and setOption. e.g.:
public static <T> void setOption(Socket s, SocketOption<T> name, T value) throws IOException
 {
     if (!isSupported(Socket.class, name)) {
            throw new UnsupportedOperationException(name.name());
    }
 invokeSet(siSetOption, s, name, value);
 }

while in jdk 9 setOption and getOption of Sockets classes:

   public static <T> void setOption(ServerSocket s, SocketOption<T> name, T value) throws IOException
    {
        s.setOption(name, value);
    } .

where ServerSockets's (and other Socket's as well) setOption and getOption methods don't contain that check.

Suggested fix:

Add check to ServerSocket.java, Socket.java, DatagramSocket.java setOption and getOption methods.
