FULL PRODUCT VERSION :
JRE 1.7.0 b147 for windows XP

ADDITIONAL OS VERSION INFORMATION :
XP SP3 japanese or tiwan.

A DESCRIPTION OF THE PROBLEM :
Put a jar execute file on the desktop of the WinXP Japanese or Tiwan.
If the JRE version was jre6-27, it runs normally.
But on the jre7-b147, it does not run.

I made a folder on the HD directly,the folder name was "TEST",
and put the same jar file into the TEST folder.
The jar run even if on the jre7-b147.
 
C:\TEST\foo.jar : run
(Desktop folder on Japanese or Tiwan WinXP)\TEST\foo.jar : don't run
I think the Desktop folder name includes 2-byte letters.


REGRESSION. Last worked in version 7
