Re: [rules-users] StackOverflow when serializing KieBase

[Federico Bertola]

I'll try to investigating a bit (or at least I'll try to make something 
reproducible). Meanwhile, this is the stack trace. It seems to me that 
is not the case as https://issues.jboss.org/browse/JBRULES-2335.
Any help is appreciated.

Federico.

It should work, there should not be too much recursion. I’d suggest digging 
deeper to see if you can point us to the references that are suspect.

Hi all,
when I try to serialize a rather large KieBase I constantly get the
aforementioned error. After a bit of tracking I see that the error seems
to appear when the KnowledgeBase try to serialize the Rete object.
I belive this is not an infinite loop because it seems that the graph is
quite deep and the serializer recursively calls writeExternal in a (sort
of) depth-first fashion.

Increasing the stack size didn't really help, so I'm asking if there's a
better way or if I should give up.

Thanks :)

Federico.
