Subject [jira] Commented: (LUCENE-819) NullPointerException in Term.compareTo()
Date Wed, 28 Feb 2007 01:40:05 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-819?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12476483
] 

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.
