1) Cipher.updateAAD(...) methods also calls checkCipherState(), so its javadoc should be updated as well?
2) Given the current checkCipherState() impl does not check for states for NullCipher objects, do we want to also update the javax.crypto.NullCipher class javadoc to mention that IllegalStateException is not thrown by various methods?
3) Update copyright year to 2023?
