PublisherAsStream gets stuck if idle-timeout is reached

[RealTYPICAL]

Expected Behavior

If the read idle timeout is reached then it appears as though the PublisherAsStream class then returns -1 on its next read method. If this happens when the micronaut.server.idle-timeout is reached then I suppose it should do the same thing.

Actual Behaviour

The thread gets stuck at: /io/micronaut/http/netty/PublisherAsBlocking.java:160. The read idle timeout also doesn't seem to trigger in this circumstance.

Steps To Reproduce

private final HttpServerConfiguration configuration;

	@Inject
	public UploadController(HttpServerConfiguration configuration) {
		this.configuration = configuration;
	}

	@Post(consumes = MediaType.ALL)
	@ExecuteOn(TaskExecutors.IO)
	@RequestLengthLimit(RequestLengthLimit.NO_LIMIT)
	public final HttpResponse uploadBytes(@Body InputStream body) throws InterruptedException, IOException {
		Thread.sleep(configuration.getIdleTimeout().toMillis() + 1000); //set micronaut.server.idle-timeout to something low like 5s (default 5m)
		body.transferTo(OutputStream.nullOutputStream());
		System.out.println("Unreachable");
		return HttpResponse.noContent();
	}

I found that the above code reproduces the problem as long as I used a 90kb worth of data. For smaller data it seemed to work better.
