Andi Huber resolved ISIS-1960.
------------------------------
Resolution: Fixed
We extended BackgroundServiceDefault, such that for background execution it
falls back to the new ForkingInvocationHandler in case there is no (developer
provided) BackgroundCommandService available.
That way we don't break the previous behavior.
> Action background execution: provide built-in default implementation

> Key: ISIS-1960
> URL: https://issues.apache.org/jira/browse/ISIS-1960
> Project: Isis
> Issue Type: Improvement
> Components: Core
> Reporter: Andi Huber
> Assignee: Andi Huber
> Priority: Major
> Fix For: 2.0.0-M1
>
>
> 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.
