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?

According to this guide:
I’ve been asked whether Java’s Cryptography/Security extension (JCE) is supported in OpenJDK. The answer is yes it is. As a note, in OpenJDK as of 8b161, unlimited cryptography policy is enabled by default (previously you had to download the unlimited strength files manually from Oracle).
