So in the case of Apache HTTPClient (which I would call a library), are you saying that it is a design flaw that it provides logging statements of its internals, when provided the proper configuration/logging implementation? If so, I would have to disagree based on pragmatic grounds, unless you have another credible way to acquire the information present in http wire logging or connection pool events, for example.
