We debugged the test and traced the error back to a call to checkValidity() in
AbstractRuleBase.java around like 435. If we comment out this call, we can continue with
the debug and see that the three variables appear to be properly placed on the child rule
object, but not before the validation check. However, running this way leads to a
separate error and stack trace.
