Camel rest route not returning status code on exception

I have created a camel route with the following exception handling:

onException(BadRequestException.class)
    .handled(true)
    .process(exchange -> {
        System.out.println("Reached processor");
        System.out.println(exchange.getIn().getBody(String.class));
    })
    .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(HttpStatus.BAD_REQUEST));

I make a request to http://localhost:8080/services/rest/endpoint?key=value

In a bean, I have some validation that says that two query parameters are required, key and keyTwo. keyTwo isn't present, so I throw a BadRequestException:

public void assertRequiredParametersPresentOnExchange() throws BadRequestException {
    try {
        requiredParameters.stream()
            .forEach(p -> assertNotNull(p));
    } catch (IllegalArgumentException e) {
        throw new BadRequestException(e.getMessage());
    }
}

When I execute the URL, I can see Reached processor output from the exception handler above, but then nothing happens. Postman waits for a reply for ~60 seconds and then gives me status code 23.

What am I missing here? MEP? Setting some property on the exchange?

It seems like you are getting the enums ordinal which is 23. Could you try to replace the the enum

org.apache.http.HttpStatus.SC_BAD_REQUEST

instead of 

org.springframework.http.HttpStatus.BAD_REQUEST

and see if it makes any difference
