title: Spring RestTemplate throws always Exception if Http status is 500
body: <p>Is it possible to use Spring RestTemplate without using Exceptions to handle http response with status 500?</p>
  
  <pre><code>        RestTemplate restTemplate = new RestTemplate();
          try {
              response = restTemplate.getForEntity(probe.getUrl(), String.class);
              boolean isOK = response.getStatusCode() == HttpStatus.OK;
              // would be nice if 500 would also stay here
          }
          catch (HttpServerErrorException exc) {
              // but seems only possible to handle here...
          }
  </code></pre>
