I'm frankly _horrified_ to learn that BitcoinJ ships its own root CA certificates bundle. This means that, if a root CA gets breached and a certificate gets revoked, all BitcoinJ-using software will be vulnerable until BitcoinJ ships an update *and* the software in question pulls in the new BitcoinJ update and releases its own update. That might never happen.
