Resource name -> URL -> URL path component.  A URL path component is not 
a file path. For file URLs then it encodes a file path (at least file 
paths that are not located on the network). There's a warning in the URL 
javadoc on this but maybe it's time to deprecate URL::getPath (in time 
we need to deprecate all of URL constructors and several methods but 
that is a topic for another day). For the example, change getPath to 
toURI so you get a URI rather than a String and it should work.
