Marked as reviewed by plevart (Reviewer).
I think this looks good. Reviewed. Only a minor nit if you think it would be
better, but not necessary if you don't. The following combo:
Boolean result = Caches.subclassAudits.get(cl);
assert result != null;
could be written as:
boolean result = Caches.subclassAudits.get(cl);
...and it would give the same "message" to the reader. WDYT? No need for
another round of reviews if you change this.
