Dan Zivkovic commented on LUCENE-819:
-------------------------------------
Empty string or null would be the same thing from the point of view of our
application. And it would be preferable to an exception coming from a place
that didn't use to throw one.
I still don't see the big deal in checking for null, however. If the fix is
simple and it's tested and it doesn't affect anyone who does NOT have nulls in
their terms, then why not just apply the patch and move on?
