Buggy source:

Fixed version (ground truth):

    if (subLists != null && subLists.size() > 1) {
      getBooksList(author,aurl,doc,apath,mainAuthor);
      return;
    }
    Elements booksList=doc.getElementsByTag("String_Node_Str");
    int count=0;
    String bookname="String_Node_Str";
    if (booksList != null) {
      for (      Element bookItem : booksList) {
        String bookText=bookItem.getElementsByTag("String_Node_Str").attr("String_Node_Str");
        if (bookText.contains("String_Node_Str"))         continue;
        bookname=bookItem.text();
        if (skipBooks.contains(bookname))         continue;
        if (authorNames.contains(bookname) || (bookname.toLowerCase()).equals(mainAuthor.toLowerCase()))         continue;
        getBooks(bookname,bookText,apath,mainAuthor);
        count++;
      }
    }
    if (count == 0) {
      if (doc.select("String_Node_Str") != null && doc.select("String_Node_Str").size() > 0)       bookname=doc.select("String_Node_Str").first().text();
