Rob Audenaerde closed LUCENE-5139.
----------------------------------
Resolution: Won't Fix
The issue cannot be fixed in Lucene, I think. So closed with 'Wont't fix'
> ArrayIndexOutOfBoundsException in FacetsAccumulator.accumulate while indexing
> -----------------------------------------------------------------------------
>
> Key: LUCENE-5139
> URL: https://issues.apache.org/jira/browse/LUCENE-5139
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/facet
> Affects Versions: 4.4
> Environment: Ubuntu 64 bit
> Reporter: Rob Audenaerde
> Attachments: testfacetindexing.zip
>
>
> It is a hard to reproduce problem, but I see it from time to time. I am
> indexing some 100k documents and while I am doing that, I use the search and
> facet module.
> In some cases, I get an AIOOBE on the FacetAccumulator.accumulate method. See
> for example this little stacktrace:
> java.lang.ArrayIndexOutOfBoundsException: 1400222
> at
> org.apache.lucene.facet.search.FastCountingFacetsAggregator.aggregate(FastCountingFacetsAggregator.java:87)
> at
> org.apache.lucene.facet.search.FacetsAccumulator.accumulate(FacetsAccumulator.java:167)
> at
> org.apache.lucene.facet.search.FacetsCollector.getFacetResults(FacetsCollector.java:214)
> at ...
> Some more detail:
> I have a index that is being written to by an IndexWriter. The index is
> searched by a SearcherManager that uses the same Directory. The
> searcherManager has a scheduled maybeRefresh each 1000ms. When refreshing, I
> also check whether the taxonomy has changed. If so, I replace it by the new
> one. I use this code:
> {code}
> TaxonomyReader newReader = TaxonomyReader.openIfChanged( this.taxoReader );
> if ( newReader != null )
> {
> this.taxoReader = newReader;
> LOG.info( "Reopening taxonomyReader because it has changed!" );
> }
> {code}
> I will try to make it more reproducable; but maybe someone already has an
> idea on what might trigger this.
