The ``reply`` method throws an ``IllegalStateException`` if unable to determine what to reply to, e.g. the sender is not an actor. You can also use the more forgiving ``reply_?`` method which returns ``true`` if reply was sent, and ``false`` if unable to determine what to reply to.

- A reply within preRestart or postRestart must be a safe reply via `self.reply_?` because an unsafe self.reply will throw an exception when the actor is restarted without having failed. This can be the case in context of AllForOne restart strategies.
- A reply within postStop must be a safe reply via `self.reply_?` because an unsafe self.reply will throw an exception when the actor has been stopped by the application (and not by a supervisor) after successful execution of receive (or no execution at all).
