A DESCRIPTION OF THE PROBLEM :
I install Java on a English language system.
The system language is firmly set to English.

The java system control panel (com.sun.deploy.panel.ControlPanel) shows up in (horrible) Swedish. Ouch.

I use google and find your guide:
http://www.java.com/en/download/help/locale.xml
The guide does not result in any change on my machine. I.e. it fails to help me.

However, after trying everything, I find that changing the "standards and formats" makes java change its user interface language.

Here's the trouble: The "standards and formats" setting does not and has never included UI LANGUAGE setting.

Conclusion: Detecting UI language from "standards and formats" on Windows XP is completely wrong.

Solution: If the XP system does not have MUI installed, then the only setting you can auto-detect UI language from is the "Language for non-unicode programs."

The best option is to allow the user to change the language of your program explicitly, after the auto-detection (which is wrong on some systems). I could not find such an explicit language option in the Java control panel.


Sidenote 1: I am a Swedish native, but all Swedish translations of software (including java) are horrible, so I must use English or else I don't understand anything. This bug forces me to try to understand the confused translation, which is hard work. The only alternative is to set my system to English "standards and units" !

Sidenote 2: I am a long time developer of commercial user interface applications that have this functionality.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Install java on a system with English Windows XP.
2. Open Control Panel -> "Regional and Language Options"
3. Set "Standards and Formats" to any non-English language supported by java (e.g. Swedish)
4. Open Control Panel -> "Java"


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The control panel is still in English, unless I do as your documentation suggests at http://www.java.com/en/download/help/locale.xml
ACTUAL -
Swedish translation on my clear spoken, otherwise English, system.


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Set the "standards and formats" of the whole Windows XP to "English" of some locale (e.g. USA, Trinidad, New Zealand, etc.)

But then all my units are wrong!
