--------------------------------------
I added another NPE chech with revision 1378487, just to make sure the NPE fix
in DescendantSelfAxisQuery covers other scenarios as well.
> CaseTermQuery #rewrite behavior changes
> ---------------------------------------
>
> Key: JCR-3407
> URL: https://issues.apache.org/jira/browse/JCR-3407
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-core
> Reporter: Alex Parvulescu
> Assignee: Alex Parvulescu
> Fix For: 2.6
>
>
> I've ran into a DescendantSelfAxisQuery query that generates a NPE [0].
> It seems that the CaseTermQuery #rewrite behavior changed after the Lucene
> upgrade.
> In the case where there are no hist, the MultiTermQuery now returns a bunch
> of BooleanQuery(ies), which can produce null scorers.
> The pre-update behavior was to produce some ConstantScoreQuery queries.
> I'll change the rewrite method (#setRewriteMethod) to always produce a
> ConstantScoreQuery, bypassing the existing optimization in lucene, but
> enforcing a safe (no nulls) scorer behavior in jackrabbit.
> [0]
> java.lang.NullPointerException
