What would blow up if our plugin classloaders were all always child-first? Specificially,
instances of our ChildFirstPluginClassLoader class?
I'm trying to see how I can make this stuff easier. And I'm thinkig - what if
there was no choice - the plugin classloader is always child-first so it will always try
to resolve classes using the plugin jars first, and only if the plugin cannot resolve them
will it go up to its parents?
