A little nit: TokenStream.end() throws an IOException but does not need to

[Lance Norskog]

org.apache.lucene.analysis.TokenStream.end()

  public void end() throws IOException {
    clearAttributes(); // LUCENE-3849: don't consume dirty atts
    if (hasAttribute(PositionIncrementAttribute.class)) {

getAttribute(PositionIncrementAttribute.class).setPositionIncrement(0);
    }
  }


This does not need IOException.
