8.5 - IsolatedLifecycleSupervisor

Posted: Dec 16, 2013 11:03 AM

In "An IsolatedLifecycleSupervisor" it says "The IsolatedLifeCycleSupervisor will provide us with a supervisor’s base functionality that lets children survive the supervisor’s own restarts, as well as provide some extra plumbing to make that happen."

I was reading Roland Kuhn's answer to a StackOverflow question (http://stackoverflow.com/questions/20528411/prevent-akka-actor-from-restarting-child-actor) and verified that even if the parent extends IsolatedResumeSupervisor with OneForOneStrategyFactory, the children get restarted if the parent restarts.

This might be recent functionality in Akka - I was using Akka 2.2.3.

Yes, I believe that's an error in the book (and I'm not sure how it's still there -- I was hands-off the manuscript almost a year ago so my memory's not great on the nuances). There's a note previous to that page that explicitly declares that there's "no way out", but this pattern is in contradiction to that statement.
