i18n - changes to default Locale not reflected in JOptionPane etc.

Name: rmT116609 Date: 06/26/2003


FULL PRODUCT VERSION :
java version "1.4.2-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-beta-b19)
Java HotSpot(TM) Client VM (build 1.4.2-beta-b19, mixed mode)


FULL OS VERSION :
C:\>ver

Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
If the default locale is set after calling a swing component that uses UIManager properties, such as JOptionPane, the old locale is used. There is no way to force the UIManager to clear its i18n cache.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
See the sample code. Re-setting the default locale does not cause re-loading of any i18n-specific captions such as Yes, No, Cancel, etc. for the JOptionPane. Reading through the UIManager source code it looks like there is no way to force re-loading of the i18n properties once the UIManager is initialised.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The first JOptionPane should have:
Title: Wahlen Sie eine Option aus
Message: Are you sure?
Buttons: Ja, Nein, Abbrechen

The second JOptionPane should have:
Title: Select an Option
Message: Are you sure?
Buttons: Yes, No, Cancel

ACTUAL -
Both JOptionPanes are displayed with German text supplied by UIManager.
If the two Locale.setDefault calls are swapped around in the above example, both JOptionPanes are displayed with English text supplied by UIManager.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
package com.mycompany;

import java.util.Locale;

import javax.swing.JOptionPane;


public class I18nBug {
    public static void main(String[] args) {
        Locale.setDefault(Locale.GERMAN);
        JOptionPane.showConfirmDialog(null, "Are you sure?");
        Locale.setDefault(Locale.ENGLISH);
        JOptionPane.showConfirmDialog(null, "Are you sure?");
        
        System.exit(0);
    }
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
None known. The state of the UIManager inner classes responsible for caching is private, so cannot be set by a calling program.
