Marcel Reutegger commented on JCR-3481:
---------------------------------------
bq. Any ideas on what could cause this?
Previous versions of Lucene always returned a Scorer for Weight.scorer(). The
version used in Jackrabbit 2.4.2 is Lucene 3.0.3, which may return null:
http://lucene.apache.org/core/old_versioned_docs/versions/3_0_3/api/core/org/apache/lucene/search/Weight.html#scorer%28org.apache.lucene.index.IndexReader,%20boolean,%20boolean%29
I guess some of the Jackrabbit classes still assume a non-null return value.

> Key: JCR-3481
> URL: https://issues.apache.org/jira/browse/JCR-3481
> 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
> Reporter: Edgar Vonk
> Attachments: error-log.txt
>
>
> 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?
