java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0)
Java HotSpot(TM) Client VM (build 1.3.0, mixed mode)


When I run any Java program, no matter what I set the system properties
user.language and user.region to, the default locale is still en_US. Here is
an example program:

import java.util.*;

public class LocaleBug {
    public static void main(String[] args) {
        for (Iterator iter = System.getProperties().keySet().iterator();iter.hasNext(); ) {
            String key = (String) iter.next();
            if (key.startsWith("user.") || key.startsWith("java.vm.")) {
                System.out.println(key + " -> " + System.getProperty(key));
            }
        }
        System.out.println("locale is " + Locale.getDefault());
    }
}

Here is what happens when I run it with the 3 VMs on my system:

[john@localhost ~/projects/filler/locale]$ /opt/jbuilder4/jdk1.3/bin/java

As you can see, the Sun VM knows the correct language and region, and the locale
is wrong. I am guessing that the static initialiser for locale is run before the
values of the system variables are set????? The code in Locale.java is:

    static {
        String language =
            (String) AccessController.doPrivileged(
                        new GetPropertyAction("user.language","EN"));
        String country =
            (String) AccessController.doPrivileged(
                        new GetPropertyAction("user.region",""));

        /* The user.region property may be of the form country, country_variant,
         * or _variant. Since the Locale constructor takes the country value as
         * an unparsed literal, and we don't want to change that behavior, we
         * must premunge it here into country and variant. - liu 7/24/98 */
        String variant = "";
        int i = country.indexOf('_');
        if (i >= 0) {
            variant = country.substring(i+1);
            country = country.substring(0, i);
        }
        defaultLocale = new Locale(language, country, variant);
    }

which suggests that what I think should work is correct, it just doesn't.
