The guided rule editors really, really, I mean really, do not handle multiple classes with the same simple name in different packages at all well. Even if you only use a single class in a single rule (I.e. do not attempt to use x.y.z.MyClass and a.b.c.MyClass) the overall DRL being compiled can lead to issues as you're effectively creating: "import x.y.z.MyClass rule a when MyClass (...) ... end" and "import a.b.c.MyClass rule b when MyClass (...) ... end" I suspect issues to arise with class FQCN resolution in at least one of those rules. If you cannot use different simple names then my advice is to use free-form DRL for these classes; using the FQCN in the rule and exclude the imports (from the "Config" tab).
