Record persistence recovery failure.

Specified by:

recoveryFailed in interface EventSourcedBehaviorInstrumentation

Parameters:

actorRef - the ActorRef for which the recovery has failed.

throwable - the cause of the failure.

event - the event that was replayed, if any (otherwise null)

persistEventCalled

public java.lang.Object persistEventCalled(ActorRef<?> actorRef,
