Buggy source:
public ArrayList<DownloadLink> decryptIt(CryptedLink param,ProgressController progress) throws Exception {
  ArrayList<DownloadLink> decryptedLinks=new ArrayList<DownloadLink>();
  for (int retry=0; retry < 5; retry++) {
    LoadImage li=LoadImage.loadFile(getHost());

    li.load(getHost());

      String[] values=captchaCode.split("String_Node_Str");
