are all of these NOTREACHED() still necessary?

[Lalit Maganti, 2015/09/28 09:24:02]

Not really. I'll just removed them and collapse into default.

[gone, 2015/09/28 10:48:43]

Should be explicit when listing these out.  I think findbugs will complain if
you don't.  You can still collapse them into a bunch of explicitly stated cases
that are NOTREACHED, though.
