The expected behaviour for reuse of NativeChaCha20Cipher for decryption is altered to match the existing Sun implementation in ChaCha20Cipher, as updated in OpenJDK21. The following scenarios are now allowed for decryption: - Reinitialize with same key + nonce - Update AAD after a successful doFinal() without reinitializing - Update AAD after an AEADBadTagException Those scenarios are not allowed (i.e., an exception is thrown) in OpenJDK20 and earlier.
