java.nio.channels.SelectionKey.isValid() should return false if its
selector is closed.

Here is the example:

-------test.java---------
import java.io.*;
import java.nio.channels.*;

public class test {
    public static void main (String [] args) {
        DatagramChannel channel = null;
        Selector sel = null;
        SelectionKey key = null;
        try {
            channel = DatagramChannel.open();
            channel.configureBlocking(false);
            sel = Selector.open();
 
            key = channel.register(
                sel, SelectionKey.OP_WRITE);
            sel.close();
        } catch (IOException e) {
            System.out.println("Unexpected IOException");
            return;
        }
        if (key.isValid()) {
            System.out.println("false value is expected");
        } else {
            System.out.println("OKAY");
        }
    }
}

Here is the result
#java -version
