Help - Problem with Java Updating

Question

In updating to the latest version of Java - 8.45 - I must also load the Unlimited Strength encryption files.  At least, that's what the README file sez ...
Unfortunately - when I agree to the terms, and download the "Unlimited Policy" zip file, it contains the US Export Policy encryption file, and NOT the Unlimited Policy File. 
Can someone help me with what's going on here?  Thanks in advance ... !

My friend looks like that u are using javax.swing.filechooser.FileFilter class as your file filter. Nothing wrong with it, but it works only with JFileChooser and not with the java.io.File.listFiles method. for that u will have to implement the java.io.FileFilter interface.
He is the code example...
import javax.swing.*;
import java.io.*;
public class FileTest implements FileFilter {
     public static void main (String args[]) throws Exception {
          new FileTest();
     public FileTest() {
          File f = new File(".");
          File [] list = f.listFiles(this);
          for (int i = 0; i < list.length; i++) {
               System.out.println(list);
class MyFileFilter implements FileFilter {
     public boolean accept(File pathName) {
          if (pathName.isDirectory()) return true;
          String ext = pathName.getName();
          ext = ext.substring(ext.lastIndexOf(".") + 1, ext.length());
          if (ext.equals("java")) { //check for any extension you want to list
               return true;
          return false;
