FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]


A DESCRIPTION OF THE PROBLEM :
Collator instances are not being created with the
appropriate localized ruleset.  Most of the Locales I created 
collators for only had the default ruleset defining their 
collation behavior.  (I didn't test them all, but the ones 
I tested exhibited this problem)

REGRESSION.  Last worked in version 1.3.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.Get a collator via Collator.getInstance(Locale l)
(the locales I tested were JAPAN, US, and CHINESE)
2.Get the rules the collator is using ( (RuleBasedCollator)
collator.getRules();
3.Compare the rules of the locales, I just displayed them
in the system console or in a jsp page

EXPECTED VERSUS ACTUAL BEHAVIOR :
I expect to get a collator populated with a japanese
collation ruleset.  I get a collator instantiated with the
default ruleset only.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No error messages occured.  I suspect this is because the implementation of
Collator.getInstance() will catch the first ParseException thrown by creating a
localized collator, and will only print a stack trace if creating a collator
with the default ruleset fails.

(BTW I was getting a ParseException when I tried to create my own
RuleBasedCollator using the "CollationElements" retrieved directly from the
Japanese ResourceBundle "LocaleElements".

This bug can be reproduced always.
