Container Service loads information about a Resouce parent scan using:
69 this.parentUri = UriParserUtils.getArchiveUri(xnatResourcecatalog.getParent());
xnatResourcecatalog.getParent() always returns a null, causing a NPE when instantiating a Resource object with this constructor.
At the moment, this constructor is used exclusively by the Event Service command action provider when launching a resource-level command. See the convert-mask-command for a previously working example.
