Josh Elser commented on ACCUMULO-1434:
--------------------------------------
My brain must not be working -- this happens on branch 1.4, 1.4.3 and branch
1.5. It just must have been a new codepath I was executing.
Dropping priority and changing the type from bug to improvement as this was
what has always been the case.

> I called flatten() on an empty ColumnVisibility (e.g. "") and got an NPE. It
> would be nice if the class itself could handle the side-case for an empty
> colvis
