Change Language in java swing at runtime

Question

I would like to know if this is possible in java that i want to reload a swing app so that i can set locale. Im working on a swing app project where more than 5 languages used and i have already created property file for each language. Whenever user selects a new language from menu my app has to restart to change the selected language. Im totally stuck here as how to restart my swing app with my loaded vm arguments and new language.

For reference here is the website which has the same requirement as what i expect. http://teravoice.com/

After web-page loads select a link which download a jnlp and once app opens, please login with any name and in the file menu you find a sub menu "language" with 12 languages. when i click on a new language the app restarts itself with the new language and with user data (i.e. vm options).

Thank you.
