This version includes new fixes for JDK-8171830 and JDK-8165640.  Thanks for doing that.  The fix for JDK-8171830 looks fine.

For JDK-8165640, it looks like checkModuleInfo can be refactored / moved to Validator so that the validation code is consistent and shared for checking in both places (MMR validation and module-info.class).

Since it’s a separate issue, you should consider just to pushing the changeset for JDK-8172432 and JDK-8171830.   Resolve  JDK-8165640 in a separate patch that will make the review easier too.
