Yes, that's how it is going down over here as well (Mexico). The Servicio de Administración Tributaria (Revenue Administration Service) uses Java for filing tax reports and mostly everything related to Tax Stuff. This is because everything is done online, then signed by a private key which has had its public key signed by SAT, and thus has official recognition. And this can no longer be done offline (the tax filing).
So killing Java means I won't be able to report to the tax man. Oopsie!
