Hi,
Using Persistent we can save the sate of an actor , but how to save the
mailbox messages of a persistent actor.
I heard about *Durable Mailbox*. But this durable mailbox of type
*akka.actor.mailbox.filebased.FileBasedMailboxType* is not working with
persistent actor. It is throwing below exception :
Exception in thread "main" akka.ConfigurationException: configuration
problem while creating [akka://example/user/persistentActor-4-java] with
dispatcher [my-dispatcher] and mailbox [akka.actor.default-mailbox]
