        * java/security/DummyKeyPairGenerator.java (clone): Removed
        useless instanceof check.
        * java/security/DummyMessageDigest.java (clone): Likewise.
        * java/security/DummySignature.java (clone): Likewise.
        * java/security/MessageDigest.java (clone): Remove useless
        instanceof check.
        * java/security/MessageDigestSpi.java (clone): Likewise.
        * java/security/Signature.java (clone): Provide meaningful
        implementation.
        * java/security/SignatureSpi.java (clone): Likewise.
