> With Akka's actors it is important to not throw exceptions in the actor
> thread, if one does not want that the actor restarts or stops. Many of the
> Java components which are called from the actor's receive method throw
> exceptions which are not properly handled by the actor thread. Therefore, we
> have to catch these exceptions and handle them properly.
