>
> recently I cranked up TestDuelingCodecs to actually test docvalues (previously it wasn't testing it at all).
> This test is simple, it indexes the same random content with 2 different indexwriters, it just allows them
> to use different codecs with different indexwriterconfigs.
> then it asserts the indexes are equal.
> Sometimes, always on BYTES_FIXED_DEREF type, we end out with one reader that has a zero-filled byte[] for a doc,
> but that same document in the other reader has no docvalues at all.
