The incident to which you refer involved the creation of a directory
named jdk/test/closed, which conflicts with an Oracle-internal sub-repo
of closed regression tests.  It wouldn't be appropriate for a .jcheck/conf
file in an open repo to refer to a private repo, so I don't think this is
the right approach.

I'm not convinced that it's worth trying to prevent this sort of mistake
is in jcheck.  As far as I know it's happened only a few times over the
last seven years.
