I had a random look at the Webrev for TreeModelEvent.java and saw the following new code:
sb.append(Integer.toString(childIndices[counter])) Wouldn't the following be slightly more efficient? sb.append(childIndices[counter]) since Integer.toString(int) creates a temporary char[] array later copied in the StringBuilder, while StringBuilder.append(int) writes directly in the buffer internal array.
