             Summary: NPE in AnalyzingSuggester
                 Key: LUCENE-4971
                 URL: https://issues.apache.org/jira/browse/LUCENE-4971
             Project: Lucene - Core
          Issue Type: Bug
    Affects Versions: 4.1
         Environment: Windows 7
            Reporter: Alexey Kudinov


Setting maxGraphExpansions > 0 with a lot of expansions (e.g. due to synonyms).
Set<IntsRef> paths = toFiniteStrings(surfaceForm, ts2a);
paths may be null, so maxAnalyzedPathsForOneInput = 
Math.max(maxAnalyzedPathsForOneInput, paths.size()) may end with NPE
