>Description:
When LANG=fr_FR, 

date.toString() throw a null pointer exception in
DateFormatSymbols.formatsForKey 
- There is a related problem : LANG=fr_FR is not correctly
parsed (it should correspond to user.language=fr and user.region=FR)
- Workaround : set the language to en/US
>How-To-Repeat:
Test program :


import java.util.*;
public class Test {

    public static void main(String [] args) {
	System.err.println(System.getProperty("user.language"));	
	System.err.println(System.getProperty("user.region"));

	// by default, on my computer, user.language and user.region have these values
	// (because LANG=FR_fr)
	System.setProperty("user.language", "LC");
	System.setProperty("user.region", "CT");

	Date d = new Date();
	System.out.println(d.toString());
    }

}

>Fix:
The exception is thrown because the parameter res is null.
(in DateFormatSymbols.formatForKey)
This parameter is null because the constructor of DateFormatSymbols has not found gnu.gcj.text.LocaleData.
A search in the source code of libjava indicates that :
only the files 
gnu/gcj/text/LocaleData_en.java and
gnu/gcj/text/LocaleData_en_US.java
but not gnu/gcj/text/LocaleData.java which would have
been loaded by default.
