Akka - StackOverflowError during object serialization

Question

I\'m with a problem that extends for more than 2 days. When I\'m exchanging messages between actors, is accusing the JVM stack overflow.

Answer 1

The likely candidate for the problem is an object which has a reference to itself. Given your expression of the domain I suspect a child has a linked list which includes itself, or a cyclic reference. That is, one of the nodes it is linked to has a link to it in turn.

Answer 2

Are you using java.util.LinkedList, or a custom linked list of your own? If the latter, you need to write a custom writeObject() method for it that avoids the recursion that would happen if you didn't have one.
