wrong tokens output from WordDelimiterFilter when english possessives are in the text
-------------------------------------------------------------------------------------

                 Key: SOLR-1706
                 URL: https://issues.apache.org/jira/browse/SOLR-1706
             Project: Solr
          Issue Type: Bug
          Components: Schema and Analysis
    Affects Versions: 1.4
            Reporter: Robert Muir


the WordDelimiterFilter english possessive stemming "'s"  removal (on by default) unfortunately
causes strange behavior:

below you can see that when I have requested to only output numeric concatenations (not words),
these english possessive stems are still sometimes output, ignoring the options i have provided,
and even then, in a very inconsistent way.

{code}
  assertWdf("Super-Duper-XL500-42-AutoCoder's", 0,0,0,1,0,0,0,0,1, null,
    new String[] { "42", "AutoCoder" },
    new int[] { 18, 21 },
    new int[] { 20, 30 },
    new int[] { 1, 1 });

  assertWdf("Super-Duper-XL500-42-AutoCoder's-56", 0,0,0,1,0,0,0,0,1, null,
    new String[] { "42", "AutoCoder", "56" },
    new int[] { 18, 21, 33 },
    new int[] { 20, 30, 35 },
    new int[] { 1, 1, 1 });

  assertWdf("Super-Duper-XL500-AB-AutoCoder's", 0,0,0,1,0,0,0,0,1, null,
    new String[] {  },
    new int[] {  },
    new int[] {  },
    new int[] {  });

  assertWdf("Super-Duper-XL500-42-AutoCoder's-BC", 0,0,0,1,0,0,0,0,1, null,
    new String[] { "42" },
    new int[] { 18 },
    new int[] { 20 },
    new int[] { 1 });
{code}

where assertWdf is 
{code}
  void assertWdf(String text, int generateWordParts, int generateNumberParts,
      int catenateWords, int catenateNumbers, int catenateAll,
      int splitOnCaseChange, int preserveOriginal, int splitOnNumerics,
      int stemEnglishPossessive, CharArraySet protWords, String expected[],
      int startOffsets[], int endOffsets[], String types[], int posIncs[])
      throws IOException {
    TokenStream ts = new WhitespaceTokenizer(new StringReader(text));
    WordDelimiterFilter wdf = new WordDelimiterFilter(ts, generateWordParts,
        generateNumberParts, catenateWords, catenateNumbers, catenateAll,
        splitOnCaseChange, preserveOriginal, splitOnNumerics,
        stemEnglishPossessive, protWords);
    assertTokenStreamContents(wdf, expected, startOffsets, endOffsets, types,
        posIncs);
  }
{code}
