  <pre><code>                    ExecutorService executor = Executors.newFixedThreadPool(treadsNomber);
                      for (final HereMapsSpeedLimitationService task : HereMapSpeedLimitationTasksList) {
                          executor.submit(new Runnable() {
                              public void run() {
                                  try{
                                      task.taskExecute();
                                      }catch (JsonParseException e){
                                          AddressRetriever.getLogger().addException(LogLevel.CRITICAL, "Erreur :", e);
                                      }catch (SQLException e){
                                          AddressRetriever.getLogger().addException(LogLevel.CRITICAL, "Erreur :", e);
