In my springboot application, I use MultiValueMap of org.springframework.util
to send a multipart/related data.

MultiValueMap<String, String> mvMapJson =
                    new LinkedMultiValueMap<>();
            mvMapJson.add(HttpHeaders.CONTENT_TYPE, "application/json");

However, I do not want to send CONTENT_DISPOSITION in the above encapsulated multipart data.
Tried mvMapJson.remove(HttpHeaders.CONTENT_DISPOSITION), which does not seem to work.
