Yonik Seeley commented on LUCENE-819:
-------------------------------------
I really don't see a need to change any code. People aren't making mistakes
constructing Terms, this just sounds like a buggy analyzer.
Personally I'd rather not even add a check for null in the constructor for
Term... it's unnecessary extra code that precludes one from creating a Term
with a null value as an application specific marker, or a template (for
Term.createTerm()).

I think the correct place to fix this is your application.
If null and "" are synonymous to you, just fix your application to use "".
If we ever were to explicitly support "null" for termText, it seems like "no
value" would make more sense than "zero length value". (AFAIK, Lucene supports
zero length terms)
