I need a code review to throw `InvalidKeySpecException` when null is passed with `generatePublic()` and `generatePrivate()`. This change takes the opportunity to modernize the KeyFactory code by using `switch` syntax for `instanceof` checking, as well as, keeping the previous design of the implementation method handling the null case. There are existing JCK test cover this case, so no regression test is added.
