java.io.StreamTokenizer.eolIsSignificant(false) fails if ordinaryChar('n') calle

See the code fragments below:

      StreamTokenizer t;
      StringBufferInputStream aStream;

      aStream = new StringBufferInputStream("one\ntwo three\tfour");
      try {
         t = new StreamTokenizer(aStream);
         System.out.println("new tokenizer");
         t.whitespaceChars(0,9);
         t.wordChars(20, 0xff);
         t.ordinaryChar('\n');
         t.eolIsSignificant(false);
         System.out.println("set wordChars");
         t.nextToken();
         System.out.println("toString() = " + t.toString() );
         t.nextToken();
         System.out.println("toString() = " + t.toString() );
