This is a regression introduced by ~~JDK-8254717~~. @kganapureddy reported this bug.

In RSAKeyFactory.engineGetKeySpec, when the input key is a private key, the method tries to cast the key to RSAPrivateCrtKey when the keySpec class is RSAPrivateCrtKeySpec or its subclasses.

~~JDK-8254717~~ fixes all isAssignableFrom checks in engineGetKeySpec. But it introduces the regression that RSAKeyFactory.engineGetKeySpec tries to cast the private key when the keySpec is RSAPrivateCrtKeySpec or its **superclasses** (i.e., RSAPrivateKeySpec). This caused the following exception when the input key is only a RSAPrivateKey:
java.security.spec.InvalidKeySpecException: RSAPrivateCrtKeySpec can only be used with CRT keys.
