Uwe Schindler updated LUCENE-1939:
----------------------------------
Fix Version/s: 2.9.2
> IndexOutOfBoundsException at ShingleMatrixFilter's Iterator#hasNext method
> --------------------------------------------------------------------------
>
> Key: LUCENE-1939
> URL: https://issues.apache.org/jira/browse/LUCENE-1939
> Project: Lucene - Java
> Issue Type: Bug
> Components: contrib/analyzers
> Affects Versions: 2.9
> Reporter: Patrick Jungermann
> Assignee: Karl Wettin
> Fix For: 2.9.2, 3.0
>
> Attachments: ShingleMatrixFilter_IndexOutOfBoundsException.patch
>
>
> I tried to use the ShingleMatrixFilter within Solr. To test the functionality
> etc., I first used the built-in field analysis view.The filter was configured
> to be used only at query time analysis with "_" as spacer character and a
> min. and max. shingle size of 2. The generation of the shingles for query
> strings with this filter seems to work at this view, but by turn on the
> highlighting of indexed terms that will match the query terms, the exception
> was thrown. Also, each time I tried to query the index the exception was
> immediately thrown.
> Stacktrace:
> {code}
> java.lang.IndexOutOfBoundsException: Index: 1, Size: 1
> at java.util.ArrayList.RangeCheck(Unknown Source)
> at java.util.ArrayList.get(Unknown Source)
> at
> org.apache.lucene.analysis.shingle.ShingleMatrixFilter$Matrix$1.hasNext(ShingleMatrixFilter.java:729)
> at
> org.apache.lucene.analysis.shingle.ShingleMatrixFilter.next(ShingleMatrixFilter.java:380)
> at org.apache.lucene.analysis.StopFilter.next(StopFilter.java:120)
> at org.apache.lucene.analysis.TokenStream.next(TokenStream.java:47)
> ...
> {code}
> Within the hasNext method, there is the {{s-1}}-th Column from the ArrayList
> {{columns}} requested, but there isn't this entry within columns.
> I created a patch that checks, if {{columns}} contains enough entries.
