Spring @Scheduled(fixedDelay) doesn't works with @Async

Affects: 5.1.7

Code to reproduce issue:

@SpringBootApplication
@EnableAsync
@EnableScheduling
public class SpringAsyncTestApplication
{
    private static final Logger LOG = LoggerFactory.getLogger(SpringAsyncTestApplication.class);

    public static void main(String[] args)
    {
        SpringApplication.run(SpringAsyncTestApplication.class, args);
    }

    @Async
    @Scheduled(fixedDelay = 1000)
    public void test1() throws InterruptedException
    {
        LOG.info(String.format("Test 1 start: %s", Thread.currentThread().getName()));
        Thread.sleep(1100);
        LOG.info(String.format("Test 1 end: %s", Thread.currentThread().getName()));
    }

    @Async
    @Scheduled(fixedDelay = 1000)
    public void test2() throws InterruptedException
    {
        LOG.info(String.format("Test 2 start: %s", Thread.currentThread().getName()));
        Thread.sleep(1100);
        LOG.info(String.format("Test 2 end: %s", Thread.currentThread().getName()));
    }
}

Expected result: Each test1() method is started 1 second after previous test1() method ends. Each test2() method is started 1 second after previous test2() method ends. test1() and test2() methods are running in parallel;

Actual result: Each test1() method is started before previous test1() method ends. Each test2() method is started before previous test2() method ends.

Actual output:

I wrongly used task Scheduller, as I remember.
