If I remember correctly, the reason why tests passed with the initial incorrect `createNonThrowing` (returning Throwing) is due to `analyzeDispatch` calling `filterIgnoredExceptions`, which in turn calls `reevaluateBehaviour`. Since the exception set was empty, `reevaluateBehaviour` correctly reset the state to `NotThrowing`, masking the initial bug.
