someone has tried to see what happens sorting on a column that
contains null values ?
It's up to the comparator to decide how to handle (or if to handle)
null
values, though I do believe that supporting a binary search on a
list with
null values is a TODO in the code.
binarySearch() isn't actually involved here - sorting using Arrays.sort
(). I'm not sure how that method handles null values (which would be
the rows in this case), but the change I just checked in adds support
for null column values within a row.
