/**
* {@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).
*
*
* NOTE: 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.) Use an explicit "file:" prefix
* to enforce an absolute file path.
