Fixed version (ground truth):

    return;
  }
  int delim=line.indexOf(' ');
  String lineNum=line.substring(0,delim).trim();
  String lineName=line.substring(delim).replace("String_Node_Str","String_Node_Str").trim();
  try {
    int num=Integer.parseInt(lineNum);
    List<CardInfo> cards=CardRepository.instance.findCards(lineName);
    if (cards.isEmpty()) {
      sbMessage.append("String_Node_Str").append(lineName).append("String_Node_Str").append(lineCount).append("String_Node_Str");
    }
 else {
      Date lastReleaseDate=new GregorianCalendar(1900,1,1).getTime();
      CardInfo lastReleasedCard=null;
      for (      CardInfo cardinfo : cards) {
        ExpansionInfo set=ExpansionRepository.instance.getSetByCode(cardinfo.getSetCode());
        if (set != null) {
          if (lastReleaseDate == null || set.getReleaseDate().after(lastReleaseDate)) {
            lastReleasedCard=cardinfo;
            lastReleaseDate=set.getReleaseDate();
          }
        }
      }
