我需要收集swingWorker线程吗?

SwingWorker 实例。这些线程以 ThreadPoolExecutor 没有暴露。

public final void execute() {
    getWorkersExecutorService().execute(this);
}

private static synchronized ExecutorService getWorkersExecutorService()

executorService = new ThreadPoolExecutor(MAX_WORKER_THREADS, MAX_WORKER_THREADS, 10L, TimeUnit.MINUTES, new LinkedBlockingQueue<Runnable>(), threadFactory);

这些线程是守护进程,因此如果它们是程序中的最后一个线程,则程序仍将关闭。
