Subject ArrayIndexOutOfBoundsException trying to use tokenizer in Lucene 4.1
Date Tue, 26 Feb 2013 12:26:04 GMT
This works in 3.6, but in 4.1 fails whats wrong with the code

public void testTokenization() throws IOException
     {
         StringBuffer sb = new StringBuffer();


         for(char i=0;i<100;i++)
         {
             Character c = new Character(i);
             if(!Character.isWhitespace(c)) {
                 sb.append(new Character(i).toString() + ' ');
             }
         }
         System.out.println(sb.toString());
         Tokenizer tokenizer = new 
WhitespaceTokenizer(LuceneVersion.LUCENE_VERSION,new 
StringReader(sb.toString()));
         while(tokenizer.incrementToken())
         {
             System.out.println("inctoken");

         }
     }

throwing exception
