Re: [rules-users] java.lang.LinkageError

That was the root error, the rest is just drools firing its rules. So does this mean there's some sort of incompatibility in the class ShoppingCart/Rule_CSMEGBUL_b996907c25e3495a94b6b041c1c08c50? I assume this is a class that's auto-generated by drools. Is it possible that serializing the rule Package is leading to an incompatible class definition?
