This existing code compiles:

        ResponseEntity<MultiValueMap> responseEntity = null;
...
        responseEntity = restTemplate.postForEntity(serviceURL, entity,
            MultiValueMap.class);

Compiles, but the linter is unhappy: found raw type: org.springframework.util.MultiValueMap.

If I add the types of map’s key and value:

        ResponseEntity<MultiValueMap<String, Object>> responseEntity = null;

the declaration line compiles, but the call to restTemplate.postForEntity() becomes an error: incompatible types: inference variable T has incompatible equality constraints org.springframework.util.MultiValueMap<java.lang.String,java.lang.Object>,capture#1 of ? extends org.springframework.util.MultiValueMap.

How do I make it right — pleasing lint in both places?
