Jersey2: Navigating from a Resource to an instance

Question

I am attempting to answer this question: What is the Jersey 2 replacement for ResourceContext.matchResource(URI)?

I've managed to navigate from a ResourceModel to a matching Resource, but it's not clear how to instantiate the corresponding user class.

Meaning, given org.glassfish.jersey.server.model.Resource that maps to some user-defined class CompaniesResource, how do I get a CompaniesResource instance out of the Resource?

The tricky part is that this needs to invoke subresource locators with values parsed from the URI.
