+ * In Resolver 1.x line, the "system" scope represented special artifacts. In
2.x resolver testing for this scope
+ * is now delegated to consumer application. Class or component that wants to
test for this special dependency scope
+ * should use this interface, with implementation provided by consumer
application.
+ * <p>
+ * System is a special scope that tells resolver that dependency is not to be
found in any regular repository, so it
+ * should not even try to resolve the artifact from them. Dependency in this
scope does not have artifact descriptor
+ * either. Artifacts in this scope should have the "local path" property set,
pointing to a file on local system, where
+ * the backing file should reside. Resolution of artifacts in this scope
fails, if backing file does not exist
+ * (no property set, or property contains invalid path, or the path points to
a non-existent file).

Review Comment:
I think javadoc is quite clear on this matter. If you consider `null`
"system" scope, then yet, return `true` here.
> LOCAL_PATH Artifact property really belongs to "system" scope (or is at least
> very related to it)
