 A specialized implementation of FileLocationStrategy which checks whether a passed in FileLocator already has a defined URL. 
 FileLocator objects that have a URL already reference a file in an unambiguous way. Therefore, this strategy just returns the URL of the passed in FileLocator. It can be used as a first step of the file resolving process. If it fails, more sophisticated attempts for resolving the file can be made. 
Since:
