The internal use may be just to avoid to create new instances of SecureRandom.   Those use may need to use the latest updated secure random provider as well, for example the use in DSA key pair generation (DSAKeyPairGenerator.java).

With this update, I think the performance impact should be minimal and we may be able to have a uniform behavior no matter internal or external uses.
