>             Project: Jackrabbit Content Repository
>          Issue Type: Bug
>          Components: jackrabbit-core
>    Affects Versions: 2.4.2
>         Environment: Magnolia CMS 4.4.9-jr24, Jackrabbit 2.4.2, Lucene 3.0.3, XPath

> For certain XPath search queries we get nullpointerexceptions in the DescendantSelfAxisScorer#nextDoc method because the 'subScorer' var is null.
> It seems other people have the issue as well:
> http://jackrabbit.510166.n4.nabble.com/JCR-SQL2-query-NullPointerException-in-DescendantSelfAxisQuery-td4657009.html
> It seems a bit arbitrary when it occurs. It seems to occur only when we search using certain short search terms. Also it occurs on stem words when we configure to use a different Lucene analyzer in Jackrabbit (e.g. the DutchAnalyzer and searching on 'een' or 'het').
> We use a custom Jackrabbit indexing-configuration.xml but I even tried without using a indexing-configuration and also then the problem occurs. 
> Any ideas on what could cause this?
