Java Cryptography Extension (JCE) can be found here, but that page says
Current versions of the JDK do not require these policy files. They are provided here for use with older version of the JDK.
JDK 9 and later ship with, and use by default, the unlimited policy files.
Does this apply to AdoptOpenJDK 11 as well? Or is this restricted to Oracle's JDKs? How do I know they are available?
