The following new required Cipher algorithms were approved as part of JDK-8015388:

    AES/GCM/NoPadding (128)
    AES/GCM/PKCS5Padding (128)

"AES/GCM/PKCS5Padding (128)" should be removed from this list. PKCS5Padding is not a valid padding for AES. There is a bug in the JDK in which the SunJCE provider accepts PKCS5Padding as a valid padding, but it should throw a NoSuchAlgorithmException (see JDK-8180392).

Also, the required algorithms for JDK 9 were accidentally omitted for the Cipher class as part of JDK-8015388. The following should be added to the implementation requirements of the class summary:

    AES/GCM/NoPadding (128)
