+ * {@link ResourceLoader} implementation that resolves plain paths as
+ * file system resources rather than as class path resources
+ * (the latter is {@link DefaultResourceLoader}'s default strategy).
+ *
+ * <p><b>NOTE:</b> Plain paths will always be interpreted as relative
+ * to the current VM working directory, even if they start with a slash.
+ * (This is consistent with the semantics in a Servlet container.)
+ * <b>Use an explicit "file:" prefix to enforce an absolute file path.</b>
+ *
+ * <p>{@link org.springframework.context.support.FileSystemXmlApplicationContext}
+ * is a full-fledged ApplicationContext implementation that provides
+ * the same resource path resolution strategy.
