To the best of my knowledge, there is no JFS, and nobody is working on
one.

That should have answered most of your questions. Possibly you need
the -current and/or -hackers archives as well.

Softupdates with a background fsck solve the problem of wanting to
come back up quickly after a crash, which is the most common reason
people ask for a JFS.

Someone in the archives indicated that there limited testing things
worked fine. I assume Kirk has tested this as well.

One with a license that will let it be distributed in the core. That
lets out GPL'ed code, and I believe it lets out XFS as well, though
I'm not positive on that.

Whoever did the work, of course.
