Subject [jira] Commented: (LUCENE-819) NullPointerException in Term.compareTo()
Date Wed, 28 Feb 2007 18:38:56 GMT

Doug Cutting commented on LUCENE-819:
-------------------------------------

> why not just apply the patch and move on?

Two reasons: (1) most folks consider it an error to use null for a term's text, an error that
unfortunately wasn't checked in the constructor, but causes problems in the comparator, when
reading and writing, etc.--basically everywhere a term is used.  Your application only uses
such terms in comparators, so you're only concerned about that case, but there are more cases,
and if null is officially supported they should all be fixed; and (2) adding complexity to
an inner-loop comparator should not be done lightly as it may have performance implications.
