OK missing from HTTP response header

I have a webapp deployed in Tomcat 8. This is the servlet I am having problems with: 

@WebServlet(name = "Start", urlPatterns = {"/start"})
public class StartServlet extends HttpServlet {

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String requestBodyStr = request.getReader().lines().collect(Collectors.joining(System.lineSeparator()));
        StartRequest startRequest = JsonUtil.parseStartRequest(requestBodyStr);

        if (startRequest == null) {
            response.sendError(HttpServletResponse.SC_BAD_REQUEST);
            return;
        }

        response.setStatus(HttpServletResponse.SC_OK);

        String responseBody = getResponseBody();

        try (PrintWriter out = response.getWriter()) {
            out.print(responseBody);
        }
    }
}

If I make a request to this servlet then the response contains no OK status message, it is just:

HTTP/1.1 200

How do I add OK to the response?

When you do response.setStatus(HttpServletResponse.SC_OK);, it is the same as doing response.setStatus(200); (Literally, if you check it, SC_OK is just a constant with value 200). 200 is the code for OK in http. If you want to write OK manually, you have to add:

responserBody += " OK";
try (PrintWriter out = response.getWriter()) {
    out.print(responseBody);
}

but that shouldn't be useful, as 200 is already saying: The request worked as intended.
