java.util.Locale.getISO3Country() works wrong if language is not defined

Name: avC70361 Date: 03/11/98



  The java.util.Locale.getISO3Country() works wrong for locales with correct
ISO country code, but with no language specified. Instead of retuning ISO
three-letter country code it throws MissingResourceException for the locales.
It should not because a three-letter ISO country code depends on the contry only, not on the language.

Here is the test demonstrating the bug.
-----------GetISO3CountryTest.java------------
import java.util.Locale;
import java.util.MissingResourceException;

public class GetISO3CountryTest {

  static final String[] countryCodes = {
