      Description

      var english = new EnglishAnalyzer(Lucene.Net.Util.LuceneVersion.LUCENE_48);

      var whitespace = new WhitespaceAnalyzer(Lucene.Net.Util.LuceneVersion.LUCENE_48);

      var pf = new PerFieldAnalyzerWrapper(english, new Dictionary<string, Analyzer>() { { "foo", whitespace }});

      var test1 = english.GetTokenStream(null, "test"); // Does not throw

      var test2 = pf.GetTokenStream("", "test"); // works

      var test3 = pf.GetTokenStream(null, "test"); // Throws NullReferenceException

       

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