java - Ant タスクは main メソッドで正常に実行されるが、Ant 実行中に確定行後に停止する

Question

なぜそのようなアリの仕事を知っている人はいますか：

public void execute() {
    Timer timer = new Timer();
    TimerTask action = new TimerTask() {
        @SuppressWarnings("ResultOfMethodCallIgnored")
        public void run() {
            String urlsForCheckPath = arachniBinPath + "urls.txt";
            List<String> urlsForCheck;
            try {
                urlsForCheck = FileUtils.readLines(new File(urlsForCheckPath));
                if (urlsForCheck != null) {
                    for (String urlForCheck : urlsForCheck) {
                        new File(arachniLogPath).delete();
                        clearTemporary(urlForCheck);//if something remains after exceptions
                        logger.info(urlForCheck + " previous log and possibly remaining temporary files deleted.");
                        checkURL(urlForCheck);
                        urlForCheck = urlForCheck.replace("/", "-");
                        convertAndSend(urlForCheck);
                        clearTemporary(urlForCheck);
                        logger.info(urlForCheck + " temporary files deleted.");
                    }
                }
            } catch (Exception e) {
                log(e);
            }
        }
    };
    timer.schedule(action, delayBeforeStart);
}

メインメソッドでは正常に動作しますが、その後停止します

 logger.info(urlForCheck + " previous log and possibly remaining temporary files deleted.");

アリ経由の実行中に例外なく？どのように修正できますか？
