Subject [jira] Created: (LUCENE-1250) Some equals methods do not check for null argument
Date Thu, 27 Mar 2008 22:10:28 GMT
Some equals methods do not check for null argument
--------------------------------------------------

                 Key: LUCENE-1250
                 URL: https://issues.apache.org/jira/browse/LUCENE-1250
             Project: Lucene - Java
          Issue Type: Bug
          Components: Index, Search
    Affects Versions: 2.3.1, 2.3.2
            Reporter: David Dillard
            Priority: Minor


The equals methods in the following classes do not check for a null argument and thus would
incorrectly fail with a null pointer exception if passed null:
<ul>
<li>org.apache.lucene.index.SegmentInfo</li>
<li>org.apache.lucene.search.function.CustomScoreQuery</li>
<li>org.apache.lucene.search.function.OrdFieldSource</li>
<li>org.apache.lucene.search.function.ReverseOrdFieldSource</li>
<li>org.apache.lucene.search.function.ValueSourceQuery</li>
</ul>

If a null parameter is passed to <code>equals()</code> then <code>false</code>
should be returned.
