Patterns.gracefulStop - This doesn't seem to work

[Boney Sekh]

Hi,

I have been trying to use the Patterns.gracefulStop to stop an actor gracefully. I know my internal actor is stopped by verifying the postStop method is invoked.
However, the future is not returning true and is held until timeout.

Is there a bug?

Here is my code:

public class TestActor extends UntypedActor {

    private final Logger log = LoggerFactory.getLogger(TestActor.class);

    final ActorRef target;

    public TestActor( ActorRef target ) {
        this.target = target;
    }

    @Override
    public void postStop() throws Exception {
        super.postStop();
        log.info("Actor stopped...");
    }

    @Override
    public void onReceive( Object msg ) {
        if ( msg == Command.STOP_PROCESSING ) {
            log.info("Stopping actor...");
            getContext().stop( getSelf() );
        } else {
            unhandled(msg);
        }
    }

}

Code to stop:

Future< Boolean > stopped = Patterns.gracefulStop( actorRef, Duration.create( 5, TimeUnit.SECONDS ), Command.STOP_PROCESSING );
Await.result( stopped, Duration.Inf() );

Hi,

I thought I should add this. Basically this works when my TestActor is at the system level, i.e. system.actorOf. However what I am trying to do is to stop an actor which is a child of another.

Thanks,

Hi Boney,

can you create a _minimized_ code sample that is self contained and shows the perceived bug?

Hi Victor,

Thanks for your reply. While I was trying to create the sample, I realized the problem was that I was using TestActorRef and that was probably the reason. When I moved my test to using JavaTestKit, it worked fine. Your reply helped me to get to the problem and thanks for that.

Regards,
Boney
