Emil Müller created LUCENENET-615:
-------------------------------------

             Summary: PerFieldAnalyzerWrapper.GetTokenStream throws NullReferenceException
                 Key: LUCENENET-615
                 URL: https://issues.apache.org/jira/browse/LUCENENET-615
             Project: Lucene.Net
          Issue Type: Bug
          Components: Lucene.Net.Analysis.Common
    Affects Versions: Lucene.Net 4.8.0
            Reporter: Emil Müller


{{var english = new EnglishAnalyzer(Lucene.Net.Util.LuceneVersion.LUCENE_48);}}{{var whitespace
= new WhitespaceAnalyzer(Lucene.Net.Util.LuceneVersion.LUCENE_48);}}{{var pf = new PerFieldAnalyzerWrapper(_englishAnalyzer,
new Dictionary<string, Analyzer>() \{ { "foo", whitespaceAnalyzer } });}}{{var test1
= english.GetTokenStream(null, question); // Does not throw}}{{var test2 = pf.GetTokenStream(null,
question); // Throws NullReferenceException}}

 

I don't think I'm doing anything wrong, but the last line crashes with the abovementioned
exception.
