ChargeDecorator#deposit(int amount);.
> Implicit implementation of abstract decorator method with at least one
> parameter is missing

> Issue Type: Bug
> Reporter: Martin Kouba
> Assignee: Ales Justin
>
> If an abstract decorator declares abstract method and this method is also
> declared on decorated type, the container should provide an implicit
> implementation of this method that calls the method on the delegate. However
> if the method has at least one parameter implementation is missing.
