Hi Jacques,

I think there's no need to be scared :-). I agree with your analysis: conversionRate will be null, so the inner if statement can be removed.

I suggest: change the else part of the inner if to throw an exception, then create a unit test to verify the exception never happens.

> Hence we need to remove the UtilValidate.isEmpty(Object) method and provide methods that accept explicit types.  
> Scripting languages should use a facade class that provides methods for working with generic Objects or providing default behaviors.
