When default locale is not en_US, getDisplayName(), getDisplayLanguage(),
getDisplayCountry(), getISO3Language(), getISO3Country() for en_US locale
do not return correct result.

Example:

//dpyLocale.java
import java.text.*;
import java.util.*;
import java.io.*;

public class dpyLocale {

    public static void main(String[] args) {
        new dpyLocale();
    }

    public dpyLocale() {
        Locale lc = new Locale("en", "US", "");
        System.out.println(lc.toString() + " - " + lc.getDisplayName());
        System.out.println(lc.toString() + " - " + lc.getDisplayLanguage());
        System.out.println(lc.toString() + " - " + lc.getDisplayCountry());
        System.out.println(lc.toString() + " - " + lc.getISO3Language());
        System.out.println(lc.toString() + " - " + lc.getISO3Country());
    }
}
