smartcn analysis throw NullPointer exception when the length of analysed text over 32767
----------------------------------------------------------------------------------------

                 Key: LUCENE-3026
                 URL: https://issues.apache.org/jira/browse/LUCENE-3026
             Project: Lucene - Java
          Issue Type: Bug
          Components: contrib/analyzers
    Affects Versions: 3.1, 4.0
            Reporter: wangzhenghang


That all because of org.apache.lucene.analysis.cn.smart.hhmm.SegGraph's makeIndex() method:
  public List<SegToken> makeIndex() {
    List<SegToken> result = new ArrayList<SegToken>();
    int s = -1, count = 0, size = tokenListTable.size();
    List<SegToken> tokenList;
    short index = 0;
    while (count < size) {
      if (isStartExist(s)) {
        tokenList = tokenListTable.get(s);
        for (SegToken st : tokenList) {
          st.index = index;
          result.add(st);
          index++;
        }
        count++;
      }
      s++;
    }
    return result;
  }

'short index = 0;' should be 'int index = 0;'. And that's reported here http://code.google.com/p/imdict-chinese-analyzer/issues/detail?id=2,
http://code.google.com/p/imdict-chinese-analyzer/issues/detail?id=11, the author XiaoPingGao
have already fixed this bug:http://code.google.com/p/imdict-chinese-analyzer/source/browse/trunk/src/org/apache/lucene/analysis/cn/smart/hhmm/SegGraph.java
