      Description

      If i use LUCENE_VERSION >= 2.9 with smart chinese analyzer, it will crash indexwriter with any reasonable amount of chinese text.

      its especially annoying because it happens in 2.9.1 RC as well.

      this is because the position increments for tokens after stopwords are bogus:

      Here's an example (from test case), where the position increment should be 2, but is instead 91975314!

        public void testChineseStopWords2() throws Exception {
          Analyzer ca = new SmartChineseAnalyzer(Version.LUCENE_CURRENT); /* will load stopwords */
          String sentence = "Title:San"; // : is a stopword
          String result[] = { "titl", "san"};
          int startOffsets[] = { 0, 6 };
          int endOffsets[] = { 5, 9 };
          int posIncr[] = { 1, 2 };
          assertAnalyzesTo(ca, sentence, result, startOffsets, endOffsets, posIncr);
        }
