The prior version threw an error but in this refactor they are treated as an "unknown OID" and only throw a debug warning. This was addressed in https://bugs.openjdk.org/browse/JDK-8011867 but prior to this refactor the aforementioned OIDs were treated differently than unknown OIDs.

Better add a comment here that the next line is about an "unsupported" type.
