java.lang.IllegalStateException: pas un objet JSON

J'essaie d'obtenir une réponse json de SonarQube à l'aide de l'API Web SonarQube. En affectant la JsonElement à une JsonObject, j'obtiens cette erreur:

Java.lang.IllegalStateException: Not a JSON Object

Ceci est ma classe Java

@Controller
public class SonarController {

    @Autowired
    JenkinsDataService jenkinsService;
    @Autowired
    SonarDataService sonarService;
    HttpEntity<String> entity;

    @RequestMapping(value = { "/sonar" })
    public void test(HttpServletRequest request, HttpServletResponse response,ModelMap model ) throws ServletException, IOException{
        try{
            String url= "http://sbstpvmlx818:9000/api/resources?metrics=coverage,sonar&depth=1&metrics=ncloc";
            RestTemplate restTemplate = new RestTemplate();

            HttpHeaders headers = new HttpHeaders();
            headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
            entity = new HttpEntity<String>("parameters", headers);
            ResponseEntity<String> sonarResponse = restTemplate.exchange(url, HttpMethod.POST, entity, String.class);

            JsonElement jelement = new JsonParser().parse(sonarResponse.getBody());
            JsonObject  jobject = jelement.getAsJsonObject();
        } catch(Exception e) {
            e.printStackTrace();
        }

    }
}

Voici ma réponse Json

lu comme JSONArray pour lire jsonarray

 if (jelement instanceof JsonObject) {
    JsonObject  jobject = new JsonObject(jelement .getAsJsonObject());
 } else if (jelement instanceof JsonArray) {
    JsonArray  jarray =  new JsonArray(jelement.getAsJsonArray());
 }

Ce n'est pas un objet JSON: [{"id":2772,"uuid":"AVeKDMBLuPlc0jzh2Dos"..... Dans votre point de départ de la réponse de l'API, JSONArray n'était pas un JSONObject. Vous avez donc Java.lang.IllegalStateException: Not a JSON Object:, ajoutez la condition si @rathna répond comme ci-dessous. 

if (jelement instanceof JsonObject) {
    JsonObject  jobject = new JsonObject(jelement .getAsJsonObject());
 } else if (jelement instanceof JsonArray) {
    JsonArray  jarray =  new JsonArray(jelement.getAsJsonArray());
 }

Je pense qu'il pourrait y avoir une petite erreur dans le code de rathna . Puisque jelement.getAsJsonObject() est déjà une JsonObject, le constructeur est redondant. Voici le code qui fonctionne pour moi: 

if (jelement instanceof JsonObject) {
    JsonObject  jobject = jelement.getAsJsonObject();
 } else if (jelement instanceof JsonArray) {
    JsonArray  jarray = jelement.getAsJsonArray();
 }
