Segment Executor not running in background

I have an api like this
```
@GetMapping("/async-test")
public String api2() throws InterruptedException {
log.info("Before async");
myService.myAsync();
log.info("after async");
return "nothing important";
}
```

And myService.myAsync implementation like this

```
@Async
public void myAsync() {
CompletableFuture.supplyAsync(() -> {
try {
log.info("before thread ....");
Thread.sleep(3000);
log.info("after thread ....");
} catch (InterruptedException e) {
throw new IllegalStateException(e);
}
log.info("before returning result ....");
return "Result of the asynchronous computation";
}, SegmentContextExecutors.newSegmentContextExecutor());
}
```

The issue here is that API waits for 3 seconds to reply when using SegmentContextExecutors.newSegmentContextExecutor(), but if I remove the segment executor, the function run in the background successfully, but for sure I lose the segment logging.

So what should be done to fix this ?
Tech stack
Spring boot v.2.7.2
Java 11
Aws x-ray v.2.11.2

Start by reproducing the /async-test endpoint with @Async and SegmentContextExecutors.newSegmentContextExecutor(), comparing it with CompletableFuture.supplyAsync without that executor. Trace why the request waits for three seconds and verify that the resolved behavior returns promptly while retaining segment logging.
