UMLImporter currently locates numerous pathmap references by linear search of a non-trivial number of known resources with a URI normalization for each resource.

If UMLImporter.createResourceSet() invokes 				

if (resourceSet instanceof ResourceSetImpl) {
  ResourceSetImpl resourceSetImpl = (ResourceSetImpl) resourceSet;
  Map<URI, Resource> uriResourceMap = resourceSetImpl.getURIResourceMap();
  if (uriResourceMap == null) {
    resourceSetImpl.setURIResourceMap(new HashMap<URI, Resource>());
  }
}

the hashed map can be exploited.

(Perhaps not appropriate to migrate to EMF where the number of resources and references may be fewer.)
