> We want this code to run out-of the box (without the need for developers to provide their own implementation of *BackgroundCommandService*) ...
> {code:java}
> @Inject private BackgroundService2 backgroundService;
> @Action
> public SimpleObject runSlowlyInBackground(){
> 	backgroundService.execute(this).runSlowly();
> 	return this;
> }
>     
> @Action
> public SimpleObject runSlowly(){
> 	try {
> 		Thread.sleep(8000); // wait 8s
> 	} catch (InterruptedException e) {
> 		e.printStackTrace();
> 	}	
> 	
> 	val dummy = new SimpleObject();
> 	dummy.setName("Dummy");
> 	
> 	repositoryService.persist(dummy);
> 	
> 	return this;
> }
> {code}
> We solve this using a default ExecutorService to run Action invocations in the background.
