> IndexWriter#updateDocValues can break index sorting if it is called on a field that is
used in the index sorting specification. 
> TestIndexSorting has a test for this case: #testConcurrentDVUpdates 
> but only L1 merge are checked. Any LN merge would fail the test because the inner sort
of the segment is not re-compute during/after DV updates.
