• Removed Deprecated java.security.acl APIs (JDK-8191138) (we don't use these)
• SunJCE provider now throws NoSuchAlgorithmException for AES/GCM/PKCS5Padding (JDK-8180392)
• Default (XML Transform) ErrorListener No Longer Reports Warnings and Errors to the Console (JDK-8228854) (I'm guessing we don't ever use the default)

• Remove the default keytool -keyalg value (JDK-8214024) (–keyalg is now required, no default: not relevant to us if we're generating keys the hard way)
