Let's say a project uses the link:https://hc.apache.org/httpcomponents-client-ga/[HttpClient library] for performing HTTP calls. HttpClient pulls in link:https://commons.apache.org/proper/commons-codec/[Commons Codec] as transitive dependency with version 1.10.

The _public_ constructor of `HttpClientWrapper` uses `HttpClient` as a parameter, so it is exposed to consumers and therefore belongs to the API. Note that `HttpGet` and `HttpEntity` are used in the signature of a _private_ method, and so they don't count towards making HttpClient an API dependency.
