Well, yes, true. We already know that the TCK runs on the honour
system, and a strict mathematical interpretation of correctness isn't
possible. The point is that a Java implementation must pass the TCK
in all modes: it is up to an implementer to run the tests as much as
necessary to establish that beyond reasonable doubt.
We cannot test all possibilities: it isn't even possible even to test
exhaustively a 64*64-bit multiplication, we already know that.
