Re: [rules-users] StackOverflow when serializing KieBase
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.

We will not be able to help you, without a unit test that demonstrates your problem.

[rules-users] Api changes from drools 5.0.1 to 6.0.1??
We are upgrading our application from drools 5.0.1 to drools 6.0.1 Final. I noticed there are significant API changes. Many classes that used to be in org.drools appear to be now in org.drools.core. Also, some classes appear to be gone: DebugRuleFlowEventListener, RuleAgent. My question is: is there a documentation somewhere explaining the API differences between the two versions? If there is no such documentation - can anyone advise what to do about DebugRuleFlowEventListener and RuleAgent?
