10.1.3 Can't not launch Update Wizard in Japanese environment.

Question

I have installed JDeveloper 10g (10.1.3) J2EE Edition Developer Preview on Japanese environment.
And I wish install ADF Faces components.
I try the installation according to the document.
Adding Custom JSF Components to Oracle JDeveloper 10g (10.1.3) Preview
http://www.oracle.com/technology/products/jdev/101/collateral/101/adffaces/howto_customcomponents.html
I select the Help menu and click on the "Check for Updates ..." menu option.
The Check for Updates Wizard is not launched.
It was the same also in Windows and Linux.
I have a workaround in Linux.
JDeveloper is started in an English environment.
Examples: % LANG=C /usr/local/JDeveloper/jdev/bin/jdev
But I have no idea on Windows.
Then I want to update in a Japanese environment.
Isn't there method by which update can do in a Japanese environment?
I get Exception StackTrace in Linux console.
java.lang.NullPointerException
