How to release resources

[hnuuhc]

Code:

public static boolean audioVideoMerge(@NotNull String audio, @NotNull String video, @NotNull String output) {
		boolean success = false;
		try (FileOutputStream fos = new FileOutputStream(output); 
                            DataSource videoDataSource = new FileDataSourceImpl(video); 
                            DataSource audioDataSource = new FileDataSourceImpl(audio)) {
			Movie countVideo = MovieCreator.build(videoDataSource);
			MovieCreator.build(audioDataSource).getTracks().forEach(countVideo::addTrack);
			Container out = new FragmentedMp4Builder().build(countVideo);
			out.writeContainer(fos.getChannel());
			success = true;
		} catch (Exception e) {
			e.printStackTrace();
		}
		new File(audio).delete();
                new File(video).delete();
		return success;
}

Result:
audio file exists
video file exists

Is this a bug?
Must use System.gc() and wait time to delete.
