I followed the hello world sample and having this runtime error:

Exception in thread "pool-1-thread-1" java.lang.RuntimeException: uncaught exception from null when processing message ServiceActor.startTransaction(ServiceImp{totalRequestCount=0, totalStatisticsRequestCount=0, totalStatisticsStartTime=0, failedRequestCount=0, latency=0, interfaceName='test', port=12345, protocol='junit', serviceDescription='default desc', apiName='0', usedThreads=0}, 125)

... 6 more

Any ideas what I'm doing wrong?

Here is my code:

Class parameters:

    public static final ExecutorService actorsThreadPool = Executors.newCachedThreadPool();
    public static ActorThread actorThread = null;
    public static final ActorRef<CommunicationInfo.ServiceActor> serviceActor = createServiceActor(actorsThreadPool);
    public static final CommunicationInfo.ServiceActorImpl serviceActorImpl =  new CommunicationInfo.ServiceActorImpl();


and the init method:



private static ActorRef<CommunicationInfo.ServiceActor> createServiceActor(ExecutorService actorsThreadPool) {
        Actors actors = new MultiThreadedActors(
                actorsThreadPool,
                new DynamicEventizerProvider(),
                new CrashEarlyFailureHandler(),
                new NullMessageListener()
        );

        actorThread = actors.startActorThread();
        ActorRef<CommunicationInfo.ServiceActor> srvActor = actorThread.bindActor(CommunicationInfo.ServiceActor.class, serviceActorImpl);
        return srvActor;
    }

Looks like serviceActorImpl is not yet initialized before you call
bindActor with it - it's still null at that point in time. Your code
initializes it only after calling createServiceActor.

Thanks. I created the Impl statically and it should have been first.

Seems to work fine now.
