> 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:
> - org.apache.lucene.index.SegmentInfo
> - org.apache.lucene.search.function.CustomScoreQuery
> - org.apache.lucene.search.function.OrdFieldSource
> - org.apache.lucene.search.function.ReverseOrdFieldSource
> - org.apache.lucene.search.function.ValueSourceQuery
> If a null parameter is passed to equals() then false should be returned.
