To reproduce:
----->
OS: Windows 7 Professional 64bit Japanese
JRE: 7u2
1. Create a folder whose path includes two-byte character
e.g. C:\������>
2. Put a demo jar file under this folder
3. Launch demo jar file
C:\������>Java2Demo.jar
or
Double click demo jar file directly at Explorer
<-----
The jar file never be executed.
If folder name is changed to english character, the problem will disappear.
There were several crucial points missing to reproduce the problem:
1. JA locale needs to be set.
2. The command must be executed as java -jar c:/XXX/Notepad.jar
*and* in a cmd.exe, running with shells mks or cygwin will
always fail.
