FULL PRODUCT VERSION :
1.7.0-b147

ADDITIONAL OS VERSION INFORMATION :
Windows 7 x64 SP1

EXTRA RELEVANT SYSTEM CONFIGURATION :
English version of windows, Swedish locale configured.

A DESCRIPTION OF THE PROBLEM :
Locale#getDefault returns the en_US locale with jdk 1.7.0-b147, whereas jdk 1.6.0_27-b07 correctly returns sv_SE.

This is also evident when running System.getProperties().list(System.out):
jdk 1.7.0-b147 list the property user.country=US
whereas 1.6.0_27-b07 properly list the property user.country=SE

Locale.getDefault(Locale.Category.FORMAT) properly returns sv_SE
Locale.getDefault(Locale.Category.DISPLAY) erroneously returns en_US

REGRESSION. Last worked in version 6u26

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Set the locale to Swedish.


REPRODUCIBILITY :
This bug can be reproduced always.
