Java WatcherService会导致线程或内存泄漏吗？

Question

我正在使用java java.nio.file.WatchService监视目录并怀疑内存泄漏。有人可以确认以下代码是否正确，或者会导致内存/线程泄漏吗？我不会在任何地方关闭监视程序。可以是一个问题吗？仅供参考，我正在使用jdk8。

 public void run() throws InterruptedException {
    while (true) {
        logger.info("Checking for file to be created in landing directory, dir: " + landingFolderStr);
        WatchKey watchKey = watcher.take();
        logger.info("Got file in landing directory, start processing");

        for (WatchEvent<?> event : watchKey.pollEvents()) {
            if (event.kind() == StandardWatchEventKinds.OVERFLOW) {
                logger.warn("Watch event might have been lost or discarded, need to investigate.");
            } else if (event.kind() == StandardWatchEventKinds.ENTRY_CREATE) {
                logger.info("Got new landing file in: " + landingFolder + ", start processing...");
                // Ingest data for thoughput and rlr
                processHandlerOutput(landingFolder, discardFolder);
            }
        }

        if (!watchKey.reset()) {
            logger.error("Exiting since file system events (WatchKey - " + watchKey + ") are no longer acessible.");
            break;
        }

}
