> We try to start more than 8 services by ServiceActivator.
> We follow hasingleton quickstart.
> Server startup is blocked on Linux but not on windows (?!?).
> If we introduce a delay of e.g. 1 second, all services start correctly also on Linux:
> public void activate(ServiceActivatorContext context) {
>   ESMSSingletonServiceBase<T> service = getSingletonService();
>   log.info("ESMSService will be installed: " + service.getSingletonServiceName());
>   SingletonService<String> singleton = new SingletonService<String>(service.getSingletonServiceName(), service);
>   singleton.build(new DelegatingServiceContainer(context.getServiceTarget(), context.getServiceRegistry()))
>     .addDependency(ServerEnvironmentService.SERVICE_NAME, ServerEnvironment.class, service.env)
>     .setInitialMode(ServiceController.Mode.ACTIVE).install();
>   // TODO: diesen Workaround evtl mal beheben. 
>   // (Server startet im Moment nicht anders... zumindest nicht auf Linux! Timingproblem?)
>   try {
> 	Thread.sleep(1000);
>   } catch (InterruptedException e) {}
