FULL PRODUCT VERSION :

Java(TM) SE Runtime Environment (build 1.6.0_27-b07)

ADDITIONAL OS VERSION INFORMATION :

A DESCRIPTION OF THE PROBLEM :
Time zone abbreviations provided by TimeZone.getDisplayName() are not internationalized. The long versions are, but the short versions are not. For instance in France "Central European Summer Time" is translated to "Heure d'été d'Europe centrale". The short version in english is "CEST", but in french it should be translated to "HAEC".

After debugging through that library it appears its just getting the Time Zone display from Java's rt.jar. After looking inside there at the TimeZoneNames_fr.java this is what I am seeing (keep in mind some of this is speculation)

String[] arrayOfString15 = { "Heure d'Europe centrale", "CET", "Heure d'été d'Europe centrale", "CEST" };

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
TimeZone tz = TimeZone.getTimeZone("Europe/Paris");
System.out.println("Time Zone (Long English): " + tz.getDisplayName(true, 1));
System.out.println("Time Zone (Short English): " + tz.getDisplayName(true, 0)); // Actual Code in third party library
System.out.println("Time Zone (Long French): " + tz.getDisplayName(true, 1, Locale.FRANCE));
System.out.println("Time Zone (Short French): " + tz.getDisplayName(true, 0, Locale.FRANCE));
and the results:
Time Zone (Long English): Central European Summer Time

Time Zone (Short English): CEST

Time Zone (Long French): Heure d'été d'Europe centrale

Time Zone (Short French): CEST
I ran also ran the same code snippet using the ICU4J 4.6.1 locale SPI provider and here's the output.

Time Zone (Long English): Central European Summer Time
Time Zone (Short English): CEST
Time Zone (Long French): heure avancée d’Europe centrale
Time Zone (Short French): HAEC

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Time Zone (Long English): Central European Summer Time
Time Zone (Short English): CEST
Time Zone (Long French): heure avancée d’Europe centrale
Time Zone (Short French): HAEC
ACTUAL -
Time Zone (Long English): Central European Summer Time
Time Zone (Short English): CEST
Time Zone (Long French): Heure d'été d'Europe centrale
Time Zone (Short French): CEST

REPRODUCIBILITY :
This bug can be reproduced always.
