> The good news is this bug only exists in trunk... the bad news is it's
> been here for some time (created by accident in LUCENE-2881).  But the
> good news is it should strike fairly rarely.
> SegmentMerger sometimes incorrectly thinks it can bulk-copy TVs/stored
> fields when it cannot (because field numbers don't map to the same
> names across segments).
> I think it happens only with addIndexes, or indexes that have
> pre-trunk segments, and then SM falsely thinks it can bulk-merge only
> when the last field number has the same field name across segments.
