Fixed version (ground truth):

  Project project=ProjectManager.getInstance().getCurrentProject();
  List<IRepositoryViewObject> service=null;
  try {
    service=proxyRepositoryFactory.getAll(project,ESBRepositoryNodeType.SERVICES,true);
  }
 catch (  PersistenceException e) {
    e.printStackTrace();
  }
  if (service != null && service.size() > 0) {
    for (    IRepositoryViewObject Object : service) {
      boolean flag=false;
      ServiceItem item=(ServiceItem)Object.getProperty().getItem();
      ServiceConnection serviceConnection=(ServiceConnection)item.getConnection();
      List<ServicePort> servicePorts=serviceConnection.getServicePort();
      for (      ServicePort port : servicePorts) {
        List<ServiceOperation> serviceOperations=port.getServiceOperation();
        for (        ServiceOperation operation : serviceOperations) {
          String originaleItemLabel=operation.getLabel();
          if (originaleItemLabel.contains("String_Node_Str")) {
            String[] array=originaleItemLabel.split("String_Node_Str");
            if (originaleObjectLabel.equals(array[1])) {
              operation.setLabel(array[0] + "String_Node_Str" + newLabel);
              flag=true;
            }
          }
        }
      }
      if (flag) {
