> This is because the source array can be/ is different for each system/ JVM. So this pick
is not repeatable for example:
> {code}
>   /** 
>    * Return a random Locale from the available locales on the system.
>    */
>   public static Locale randomLocale(Random random) {
>     Locale locales[] = Locale.getAvailableLocales();
>     return locales[random.nextInt(locales.length)];
>   }
> {code}
> I don't think there is much we can do to make it repeatable (other than maybe enforcing
locale using system property).
