an security update for Java SE 6 Update 23 has been released by Oracle. so it's time for rev2 of jPortable
also, it would be nice if jPortable Launcher could work with parameters. so users can apply things like security updates manually.
the security update needed up to 2 params. -u for updating, -t for testing the update.
