the code is the following :
  import org.exoplatform.portal.webui.util.Util;  
  import org.exoplatform.services.wcm.navigation.NavigationService;

  def navigations = Util.getUIPortal().getNavigations();
  def navigationService = uicomponent.getApplicationComponent(NavigationService.class);
  def JSONnavigation = navigationService.getNavigationsAsJSON(navigations);

the method at the origin of the stack overflow :
  public String getNavigationsAsJSON(List<PageNavigation> navigations) throws Exception {
    PortalNavigation portalNavigation = new PortalNavigation(navigations);
    JsonValue jsonValue = new JsonGeneratorImpl().createJsonObject(portalNavigation);
    String JSONnavigation = jsonValue.toString();
    JSONnavigation = JSONnavigation.substring(1, JSONnavigation.length() - 1);
    JSONnavigation = JSONnavigation.replaceFirst("\"navigations\":", "");
    return JSONnavigation;
