Do I need to collect swingWorker threads when they are done?

I am using a GUI to call swing worker threads.

After they finish and excute the method done(), I am printing Thread.activeCount(). I get a number which indicates the threads are still active.

Do I need to collect them somehow when they are done?

You cannot manually destroy the threads created by SwingWorker instances. These threads run in a ThreadPoolExecutor which is not exposed.

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

private static synchronized ExecutorService getWorkersExecutorService()

You'll have to wait for the timeout. Each thread that's generated has a time-out of 10 minutes.

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

These threads are daemon, so the program will still shutdown if they're the last threads in your program.
