(yes, that's my preference, although the other way is not too terrible)

yes yes yes; the reflection should reflect what's in the class-file (or a resolvable subset), not everything in the VM's knowledge

I like Remi's idea of scrubbing the list (of reflected nestmates) of bad actors rather than clearing the list if there are *any* bad actors.

Reminder:  bad actors are an edge case, not a normal case.
Question:  what do we do in the exactly parallel case for getInnerClasses?  Do we scrub bad actors?  Nullify the result?  Throw?  (Probably throw.)
