Edgar Vonk created JCR-3481:
-------------------------------
Summary: NullPointerException in DescendantSelfAxisScorer#nextDoc
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
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?
