Hello all, I have found an interesting race condition that is quite likely due to my design when injecting an adapter which provides a ClusterClient in Play 2.5.x. Because groups don't support well-formatted code, I'll provide links to github gists.
First, my adapters <https://gist.github.com/erip/073ccc2e28090deeccfd474df5f1edd9>. The point of the adapter is to inject a cluster client for use in a controller within my Play application. Secondly, my relevant controller <https://gist.github.com/erip/ab60aaa944a04b31ad2637183309b94c>. The job of this is to simply send the string "Hello!" to my FooActor, who will in turn respond to `sender` with a "World!" message. I won't include this. Finally, the part marking my FooActor as the receptionis within the cluster: ClusterClientReceptionist(fooActorSystem).registerService(fooActor) Thread.sleep(5000) I find that occasionally I'll indeed receive World! from the cluster, which is promising. More often, however, I find that I'll receive a DeadLetters message: *[INFO] [02/17/2017 12:10:01.859] [PubSubMember-akka.actor.default-dispatcher-18] [akka://PubSubMember/system/receptionist] Message [akka.cluster.client.ClusterReceptionist$Internal$GetContacts$] from Actor[akka.tcp://[email protected]:8888/user/ClusterClient#-482763544] to Actor[akka://PubSubMember/system/receptionist] was not delivered. [1] dead letters encountered. This logging can be turned off or adjusted with configuration settings 'akka.log-dead-letters' and 'akka.log-dead-letters-during-shutdown'.* Can someone help me find why what causes the race condition? My initial guess is that there was a lazy injection with guice, so I tried to bind the FooActorAdapter as an eager singleton and it didn't work. I also added a Thread.sleep(5000) after the client is created and this didn't help either. I've been banging on this for the better part of two weeks and would love to solve this!
