Description

When using FilenameUtils#getFullPathNoEndSeparator with directories, windows and linux are returning different results.

Linux returns ".../subfolder" and windows returns "...\path".

    private static void commonsIo() {
        String result = getSubFolderFromFile(new File("C:\\path\\subfolder\\"));
        // Fails in common-io:2.11.0 b/c result is "path" instead of "subfolder".
        System.out.println("result should be \"subfolder\", but it is: " + result);
    }

    private static String getSubFolderFromFile(final File file) {
        return FilenameUtils.getBaseName(FilenameUtils.getFullPathNoEndSeparator(file.getAbsolutePath()));
    }

The result should be equal when using both OS.
