However, those changes started to become somewhat more intrusive than I'd like for this PR, which is focused on removing security-related stuff. EDIT: I've filed [JDK-8344461](https://bugs.openjdk.org/browse/JDK-8344461) to cover this additional cleanup work.

Are there any remaining uses of sun.security.util.* in java.rmi? I suspect this is the last one, in which case you can update java.base's module-info to not export this package to java.rmi.
