You are probably running with config akka.actor.serialize-messages = on
It could be fixed by TryToIdentifySingleton extends
NoSerializationVerificationNeeded, please open a pull request if you like.

[akka-user] missing serialization-bindings for ClusterSingletonProxy$TryToIdentifySingleton$ [akka-cluster-2.5.3]

2017-11-02 Thread Christophe Pache 
Hello everyone! 

I notice in our logs the following exception and would like to understand 
what is really happening:

java.io.NotSerializableException: No configured serialization-bindings for 
> class [akka.cluster.singleton.ClusterSingletonProxy$TryToIdentifySingleton
> $]


In my opinion, this message should not be sent remotely anyway, this is an 
internal message the ClusterSingletonProxy schedules to himself.  Might 
this be when ClusterSingletonProxy stops (doesn't seam to have graceful 
shutdown not scheduled message handling in case of MemberRemoved)? 

I'm pretty sure it's just a log issue as the whole system looks like 
working find, but would be really interested into getting a bit what's 
happening. Many thanks in advance!

Cheers,
Christophe
