WatchService registered directory gets deleted, but nothing happens.

[ghost]

FileSystem fs = Jimfs.newFileSystem(Configuration.unix());
Path data = fs.getPath("/data");
Files.createDirectory(data);
 
 watcher = data.getFileSystem().newWatchService();
Thread watcherThread = new Thread(() -> {
	WatchKey key;
			try {
				key = watcher.take(); // will be stuck here
				while (key != null) {
					for (WatchEvent<?> event : key.pollEvents()) {
						System.out.printf("event of type: %s received for file: %s\n", event.kind(), event.context());
					}
					boolean isValid = key.reset();
				}
			} catch (Exception e) {
				e.printStackTrace();
			}
	}, "CustomWatcher");
watcherThread.start();
data.register(watcher, ENTRY_CREATE, ENTRY_DELETE, ENTRY_MODIFY);
 
Files.deleteIfExists(data);

When the registered directory gets deleted nothing happens at all but when using the default file system WatchService.take() actually stops waiting and the WatchKey for the registered directory gets invalidated.
