Spring Boot Actuator Management Endpoint Exception Handling

Question: how can I handle exceptions thrown in MVC endpoints in management context?

public class MyMvcEndpoints extends EndpointMvcAdapter {
    @ResponseBody
    @RequestMapping(method = GET, value = "/foo", produces = APPLICATION_JSON_VALUE)
    public Foo foo() {
        throw new FooNotFound("Foo Not Found!");
    }
}

@ResponseStatus(value = HttpStatus.NOT_FOUND)
public class FooNotFound extends RuntimeException {
    public NotFoundException(String message){
        super(message);
    }
}

With the current configuration, I receive 500 instead of 404. I tried usual approaches for exception handling like ControllerAdvice, ExceptionHandler methods, etc. No success.
I also found CompositeHandlerExceptionResolver in EndpointWebMvcChildContextConfiguration which is responsible for exception handling. I tried to define my own HandlerExceptionResolver bean but it cannot find my resolver in management context.
