> Key: LUCENE-5083
> URL: https://issues.apache.org/jira/browse/LUCENE-5083
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/codecs
> Affects Versions: 4.3.1
> Environment: any
> Reporter: Adrian Nistor
> Priority: Minor

>
> The problem appears in version 4.3.1 and in revision 1498027. I
> attached a two-line patch that fixes it.
> In method "FuzzySet.getNearestSetSize", the loop over
> "usableBitSetSizes" keeps overriding "result" with
> "usableBitSetSizes[i]". Therefore, only the last written value is
> visible out of the loop and all the other writes and iterations are
> not necessary. The patch iterates from the end of "usableBitSetSizes"
> and breaks the first time when "result" is set.
