The above bug does not appear to have been resolved satisfactorily or I
don't have access to the fixed Java version.

import java.io.*;
import java.net.*;
import java.nio.channels.*;
public class OptionSupport {
 public static void main(String[] args) throws IOException {
 printOptions(SocketChannel.open());
 printOptions(ServerSocketChannel.open());
 printOptions(AsynchronousSocketChannel.open());
 printOptions(AsynchronousServerSocketChannel.open());
 printOptions(DatagramChannel.open());
 }
 private static void printOptions(NetworkChannel channel) throws
IOException {
 System.out.println(channel.getClass().getSimpleName() + " supports:");
 for (SocketOption<?> option : channel.supportedOptions()) {
 System.out.println(option.name() + ": " + channel.getOption(option));
 }
 System.out.println();
 channel.close();
 }
}

Running the above program throws the same error for Openjdk:

java -version         openjdk version "10.0.2" 2018-07-17

OpenJDK Runtime Environment (build 10.0.2+13)

OpenJDK 64-Bit Server VM (build 10.0.2+13, mixed mode)

The date of the JDK version is earlier than the resolution of the error.

I'm running Java on Arch Linux for Termux.
