If it's a file URL, then obviously you can check the protocol and create 
a `File` from the file portion. However most resources are not stored in 
naked files.

For jared resources, you can cast the URLConnection to JarURLConnection 
and call getJarFile. Some implementations of JarURLConnection may not 
return a JarFile.
