I think we agree. Let just s/serious//. It is an option. Just not one
that is IMHO feasible nor desirable for a free software project.

That is exactly my point. And you cannot prove the other way, that the
JCK tests behavior that is actually specified and not just a test for an
implementation detail. So we would be raising some smoke screen with no
way for the end user or our fellow hackers to do anything with except to
just trust those behind the NDA. They won't even be able to tell if it
is something that just happens on the particular setup that runs the TCK
or not.
