PathDelegate is supposed to actually be an instance whose provider is the platform one, Bsd in this case. 
Delegated back to when I decide the file isn't an archival one I want to handle differently. 
It goes....

pubilc abstract class AbstractPath {
// Defines helper methods as per zip demo
}

public class PathDelegate extends AbstractPath implements Path {

     Path path;		// Instance of platform, Bsd in this case, Path

// methods do their invocations on the above path instance.
// The 'helper' or convenience methods inherited from AbstractPath are what keeps this from itself being a straight pass through

}

What actually shows as the provider for this class may be the problem though, that it is actually not the Bsd one. I will look into that.

Should of known that. I did one of these myself just to make sure that the so far basic testing I have now would run correctly.
