java.net.URL allows to create URL with port < -1 and port > 65535

java.net.URL allows to create URL with port < -1 and port > 65535
After the fix of 4101492 URL(protocol, host, port, file) checks whether port is not less
than -1, but it still does not check for port is greater than 65535.

URL(String spec) does not check the port value at all.

Here is the test demonstrating the bug:

------------------------ Test.java ---------------------------------------
import java.net.*;
import java.io.*;


public class Test {

    public static void main (String args[]){
       
        int[] ports = {
                Integer.MIN_VALUE, Integer.MIN_VALUE + 1,
                -2000, -3, -2,
                65536, 65537, 100000,
                Integer.MAX_VALUE - 1, Integer.MAX_VALUE
        };

        URL url = null;
        boolean passed = true;

        System.out.println("----- URL(String spec) ------");
        for (int i = 0; i < ports.length; i++) {
            try {
                url = new URL ("http://localhost:" + ports[i] + "/");
                System.out.println("no exception with: " + ports[i]);
                System.out.println(" url created: " + url);
                passed = false;
            } catch (Exception e) {
            }
        }

        System.out.println("----- URL(proto, host, port, file) ------");

        for (int i = 0; i < ports.length; i++) {
            try {
                url = new URL ("http", "localhost", ports[i], "/file");
                System.out.println("no exception with: " + ports[i]);
                System.out.println(" url created: " + url);
                passed = false;
            } catch (Exception e) {
            }
        }


        if (passed)
            System.out.println("TEST PASSED ");
        else
            System.out.println("TEST FAILED ");

    }
}
