`Header` is a "sister" class of `Path`, `Query` and `Cookie`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Header`, and others from `fastapi`, those are actually functions that return special classes.

to the host applications ClassRealm as the parent but the search order would be child first, and the parent ClassRealm can optionally choose to limit the searching to particular classes. The application ClassRealm, or parent ClassRealm, should only expose the API in the form of and application interface and model classes that may be required by plugins.

For debugging purposes we also need to keep track of what versions of artifacts are being used so that when we are debugging in the IDE...

                 * MNG-6300: resolvedArtifacts can be cache result; this ensures reactor files are always up-to-date
                 * During lifecycle the Artifact.getFile() can change from target/classes to the actual jar.
                 * This clearly shows that target/classes should not be abused as artifactFile just for the classpath
