private void matchIdenticalMethods(ASTNode left, ASTNode right) {
    //fix in which some methods got pretty bad matches
    //feels pretty dirty though (but so does this whole file)
    for (Iterator<ASTNode> iterator = new BreadthFirstNodeIterator(left); iterator.hasNext();) {
        ASTNode n = iterator.next();/*w  w w  .j  ava  2s  .co  m*/
        ASTNode bestMatch = null;
        if (n.getNodeType() == ASTNode.METHOD_DECLARATION) {
            MethodDeclaration x = (MethodDeclaration) n;
            if (!leftMatching.containsKey(x)) {
                for (Iterator<ASTNode> rightIterator = new BreadthFirstNodeIterator(right); rightIterator
                        .hasNext();) {
                    ASTNode y = rightIterator.next();
                    if (y.getNodeType() == x.getNodeType() && x.subtreeMatch(new ASTMatcher(), y)) {
                        bestMatch = y;

                }
            }
            //we have found the best node, lets now match them together
            //afaik this is also not in the original paper, but we sometimes got some weird matches
            if (bestMatch != null) {
                markMatchedNode(x, bestMatch);
