public class FileEditor
Editor for java.io.File, to directly populate a File property
from a Spring resource location.
Supports Spring-style URL notation: any fully qualified standard URL
("file:", "http:", etc) and Spring's special "classpath:" pseudo-URL.
NOTE: The behavior of this editor has changed in Spring 2.0.
Previously, it created a File instance directly from a filename.
As of Spring 2.0, it takes a standard Spring resource location as input;
this is consistent with URLEditor and InputStreamEditor now.
NOTE: In Spring 2.5 the following modification was made.
If a file name is specified without a URL prefix or without an absolute path
then we try to locate the file using standard ResourceLoader semantics.
If the file was not found, then a File instance is created assuming the file
name refers to a relative file location.
