A couple of the `sun.security.action` classes can't be removed yet, as well as a few constants in `sun.security.util.SecurityConstants` and internal `ProtectionDomain` methods until dependencies are removed in other areas.

Hi @seanjmullan,

This is very minor/nit, but, while adapting #15539 for the upcoming changes in this PR (and the whole work in [JDK-8338411](https://bugs.openjdk.org/browse/JDK-8338411 "Implement JEP 486: Permanently Disable the Security Manager")), I found the following comments, which we will also want to remove.
