What are common mistakes developers make with WatchService (file watchers)?

// Common Mistakes When Using WatchService in Java

// 1. Not Handling Interrupted Exceptions
try {
    WatchService watchService = FileSystems.getDefault().newWatchService();
    Path path = Paths.get("path/to/directory");
    path.register(watchService, StandardWatchEventKinds.ENTRY_CREATE);

    while (true) {
        WatchKey key = watchService.take(); // This can throw an InterruptedException
        for (WatchEvent> event : key.pollEvents()) {
            System.out.println("Event kind:" + event.kind());
            System.out.println("File affected: " + event.context());
        }
        key.reset();
    }
} catch (InterruptedException e) {
    // Handle the interruption
    Thread.currentThread().interrupt(); // Restore the interrupted status
} catch (IOException e) {
    e.printStackTrace();
}

// 2. Not Resetting the WatchKey
// After processing events, it is crucial to reset the WatchKey to continue receiving events.
// Failing to do this results in missing subsequent events.

// 3. Blocking the Event Dispatch Thread
// Avoid long-running operations inside the loop that processes file events.
// Instead, consider using a separate thread or executor service.

// 4. Assuming Events Are Processed in Order
// Events can be received out of order; make sure to account for this in your logic.
