Buggy source:

  String tag=t.toString().toUpperCase();
  if (tag.equals("String_Node_Str")) {

    if (l == null || l.toString().toUpperCase().indexOf("String_Node_Str") < 0) {

Fixed version (ground truth):

  String tag=t.toString().toUpperCase();

    if (l == null || l.toString().toUpperCase().indexOf("String_Node_Str") < 0) {
      Object value=a.getAttribute(HTML.Attribute.SRC);
      if (value != null) {
        try {
          URL scriptSrc=new URL(input,value.toString());
          InputStreamReader scriptReader=new InputStreamReader(scriptSrc.openConnection().getInputStream());
          int read;
          char[] buffer=new char[1024];
          while ((read=scriptReader.read(buffer)) != -1) {
