If I do : export LANG=fr_FR
then from a java program :
"user.language" is "LC"
and "user.region", "CT"

Sun Java correctly indicate user.langage=fr user.region=FR
>How-To-Repeat:
see description

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"));
}
}

Do also :

#include <unistd.h>
#include "stdlib.h"
#include "stdio.h"
#include <locale.h>


int main(char * argv [],int args)
{

  char *locale = setlocale (LC_ALL, "");
printf(locale);
}


>Fix:
The parsing is done in natSystem.cc at line 428,
The code does : 
char *locale = setlocale (LC_ALL, ""); 
and copy the first two chars to user.language

but a small test with a c program indicates that
the result of setLocale is :
LC_CTYPE=fr_FR;LC_NUMERIC=fr_FR;LC_TIME=fr_FR;LC_COLLATE=C;LC_MONETARY=fr_FR;LC_MESSAGES=fr_FR;LC_PAPER=fr_FR;LC_NAME=fr_FR;LC_ADDRESS=fr_FR;LC_TELEPHONE=fr_FR;LC_MEASUREMENT=fr_FR;LC_IDENTIFICATION=fr_FR

so the code parse "LC_CT" instead of "LC_NM".

A quick verification on a HP UX 10.20/GCC 2.7.2.2 indicates
that the result of setLocale is fr_FR.roman8 fr_FR.roman8 fr_FR.roman8 fr_FR.roman8 fr_FR.roman8 fr_FR.roman8
(with LANG=fr_FR.roman8)

So the best way to proceed it probably :
to look for the string "=", if present start the parsing after
the "="
otherwise, do a before
