Netbeans 7.2.1 change user interface language

I've setup a Netbeans IDE 7.2.1 and by default it's user interface uses your system language. Sometimes it's good, but i prefer to see the IDE in English.

So, let's fix it. Open the <netbeans_install_dir>/etc/netbeans.conf and change the line netbeans_default_options. Append to the end of it "-J-Duser.language=en -J-Duser.region=US". Restart your IDE and you will see english interface.
