Update 02/05/2018 (about 4 years later)...I tested this again as people have been upvoting my question/answer and Sotirios Delimanolis is correct that I should not have to write the code in my answer to make this work. I used basically the same RestTemplate/REST service setup as shown in my question with the REST service having a confirmed response content type of application/json and RestTemplate was able to process the response with no issues into a Map.

I ended up getting the contents as a String and then converting them to a Map like this:

String json = restTemplate.getForObject(buildUrl, String.class);
Map map = new HashMap();
ObjectMapper mapper = new ObjectMapper();

try {
    //convert JSON string to Map
   map = mapper.readValue(json, new TypeReference>(){});
} catch (Exception e) {
     logger.info("Exception converting {} to map", json, e);
}

return map;
