I think that is how it is implemented. Exception from preStart results in clearing the actor field and throwing ActorInitializationException: https://github.com/akka/akka/blob/master/akka-actor/src/main/scala/akka/actor/ActorCell.scala#L599
Default supervision will result in stop, but postStop is not called because the actor field was cleared: https://github.com/akka/akka/blob/master/akka-actor/src/main/scala/akka/actor/dungeon/FaultHandling.scala#L210 On Wed, Mar 30, 2016 at 10:59 AM, Endre Varga <[email protected]> wrote: > > > On Sun, Mar 27, 2016 at 5:52 PM, Stanislav Savulchik < > [email protected]> wrote: > >> Hi, everyone! >> >> I've discovered that Actor's postStop method doesn't get invoked if >> exception occurs during actor initialization via preStart method.
