You're asking it a question - "does FileUtils exist or not" - that it
is not intended to answer, and that it doesn't claim to be able to
answer.

What it can do, however, is tell you that it looks like FileUtils might
not exist.  And that would help in a whole lot of cases, no matter how
many pathological counterexamples you can come up with.
