Controller method return type is properly set only for wrapper types

[Unstopabul]

If a KafkaListener method looks like this:
java.util.concurrent.CompletableFuture<ExampleOut>handleExampleIn(@Payload ExampleIn examplein, @Headers Map<String, String> headers);

the resulting controller method looks like this (returning type is ExampleOut which is correct):
public ExampleOut executeExampleIn(@RequestBody ExampleIn examplein,
@RequestParam @Parameter(hidden = true) Map<String, String> params,
HttpServletResponse servletResponse, @RequestHeader Map<String, String> headers) {
kafkaSenderService.send(topicName, examplein, params, servletResponse);
return new ExampleOut();
}

But if a KafkaListener method doesn't use wrappers for the returning type:
ExampleOuthandleExampleIn(@Payload ExampleIn examplein, @Headers Map<String, String> headers);

the resulting controller method return type will be void.
