Major Description
org.apache.wicket.request.resource.PackageResourceReference.lookupStream(IResourceStreamLocator, Locale, String, String) asks the IResourceStreamLocator to find the IReqourceStream with these parameters but this locator may return a ResourceReference with a weaker Key, e.g. ignored Locale: the lookup is for (Some.class, "some.css", Locale.US) but the result is (Some.class, "some.css").
StreamInfo should use the returned IResourceStream's settings (locale, style, variation) instead of the searched ones.
