java.net.InetAddress.getByName(host) works incorrectly with illegal IPv6 addresses
if SecurityManager is set. It throws IllegalArgumentException instead of
UnknownHostException.

This is the test demonstrating the bug:
------------------------------------------------------
import java.net.*;
import java.io.*;


public class Test {

    public static void main (String args[]){
       

        SecurityManager sm = new SecurityManager();
        String strAddr = "::FFFF:127.0.0.1.2";

        System.out.println("SecurityManager is not set ");
        try {
            InetAddress addr = InetAddress.getByName(strAddr);
        } catch (Exception e) {
            e.printStackTrace(System.out);
        }

        System.out.println("==================================");
        System.out.println("SecurityManager is set ");

        System.setSecurityManager(sm);

        try {
            InetAddress addr = InetAddress.getByName(strAddr);
        } catch (Exception e) {
            e.printStackTrace(System.out);
        }

    }
}

output from the test:

==================================
SecurityManager is set
java.lang.IllegalArgumentException: invalid port range: :FFFF:127.0.0.1.2
        at java.net.SocketPermission.init(SocketPermission.java:317)
        at java.net.SocketPermission.<init>(SocketPermission.java:207)

        at java.net.InetAddress.getByName(InetAddress.java:679)
        at Test.main(Test.java:26)



The reason of this bug is if SecurityManager is set then SocketPermission ctor is
invoked by checkConnect() method. But checkConnect() does not enclose host in []
before pass to SocketPermission.
