Shai Erera updated LUCENE-1250:
-------------------------------

        Lucene Fields: [New, Patch Available]  (was: [New])
    Affects Version/s:     (was: 2.3.2)
                           (was: 2.3.1)
        Fix Version/s: 4.0
                       3.1

This is now only applicable to OrdFieldSource and ReverseOrdFieldSource. I'll fix both of them.

> 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.
