> File.getCanonicalPath is very time cost and is heavily used by checking file permission. But in the most of cases, the canonical path is never change, it's better to cache them to avoid calculate every time. And I found RI also has cache: File.getCanonicalPath doesn't reflect change in file system real-time.
