Unable to start actor in init method

I am observing a problem that when I try to create an actor and send a message to it using Spring's @PostConstruct I get a NPE exception. If I create an actor from a method call and send a message to an actor then it works. Is this a known limitation?

Trying to use similar method, failing?

I am trying to use this method of a Spring "extension". In my Spring java config class I have a bean defined like

... public class TestActor extends UntypedActor {...

@Bean
public TestActor testActor() {
    return new TestActor();
}

Then I have a spring unit-test that loads off this Java config and does...

ActorRef testActor = myAkkaSystemBean.actorOf(SpringExtProvider.get(system).props("TestActor"),"TestActor");

Then I get this exception:

Caused by: akka.actor.ActorInitializationException: You cannot create an instance of [org.bitsofinfo.coredata.experimental.akka.TestActor] explicitly using the constructor (new). You have to use one of the 'actorOf' factory methods to create a new actor. See the documentation.

So my question is, how can I define all my actors in spring XML or java config, then just load them by name if constructing them, blows up like this?

Testing akka-java-spring integration

Well,
this code definitely works but this technique proposed here seems hard to test.

The idea of DI when it comes to testing is to be able to mock some these dependencies to test certain behaviors. It does not seem trivial to combine the technique of the SpringActorProducer with Akka's Testkit and say Mockito for testing.

Does someone have any code to promote this nice PoC from it works to works and tested?
