Dan Zivkovic commented on LUCENE-819:
-------------------------------------
We use Lucene on content that is often strange and exciting, and we get all
sorts of text fields, including nulls. This ends up throwing NPE's with no way
to resolve them except inside Lucene. I considered the possibility of a
workaround before even filing the bug, but when that proved impossible, I filed
the bug, got an Apache login, and submitted the fix.
