Fixed version (ground truth):

  RouterOperationResultObject resultObject=new RouterOperationResultObject();
  resultObject.setId(router.getId());
  resultObject.setZoneId(router.getDataCenterId());

  resultObject.setDns1(router.getDns1());
  resultObject.setDns2(router.getDns2());
  resultObject.setNetworkDomain(router.getDomain());
  resultObject.setGateway(router.getGateway());
  resultObject.setName(router.getName());
  resultObject.setPodId(router.getPodId());
  resultObject.setPrivateIp(router.getPrivateIpAddress());
  resultObject.setPrivateMacAddress(router.getPrivateMacAddress());
  resultObject.setPrivateNetMask(router.getPrivateNetmask());
  resultObject.setPublicIp(router.getPublicIpAddress());

  resultObject.setTemplateId(router.getTemplateId());

  if (router.getHostId() != null) {

    resultObject.setHostId(router.getHostId());
  }
  Account acct=managementServer.findAccountById(Long.valueOf(router.getAccountId()));
  if (acct != null) {
