I don't recall java.base ever declaring that it `provides` these providers, except maybe via a META-INF/services configuration file for a short period from the original JCE work and the dropping the service configuration files.

I think Alan is right.  They were not loaded via ServiceLoader.load because of the build complexity to get multiple service config files before the module system went in jdk9.

As it stands now, no provides java.security.Provider in java.base after JDK-8157489 is resolved.
