AccessDeniedException при запуске Files.walkFileTree

Question

Я пытаюсь пройтись по папкам и подпапкам, используя walkFileTree, и я использую Java 7. Я получаю AccessDeniedException. Я попытался @Override для visitFileFailed и изменил определение. Это не сработало.

public void getAllDirectories(File file) {

    try {
        final java.nio.file.Path p = Paths.get(file.getAbsolutePath());

        Files.walkFileTree(p, new SimpleFileVisitor<Path>() {

            @Override
            public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) {

                try {
                    File f = file.toFile();

                    if (f.isDirectory()) {
                        return FileVisitResult.CONTINUE;
                    } else {
                        System.out.println(f.getAbsolutePath());
                        return FileVisitResult.CONTINUE;
                    }
                }
                catch(Exception e) {
                    return FileVisitResult.SKIP_SUBTREE;
                }
            }

            @Override
            public FileVisitResult visitFileFailed(Path file, IOException e) {

                _log.warn("Access Permissions denied for " + file);
                return FileVisitResult.SKIP_SUBTREE;
            }
        });
    }
    catch(Exception e) {
        System.out.prinln("Error Caught: " + e.getMessage());
    }
}

В приведенном выше коде вместо обработки AccessPermissionDenied исключения методом visitFileFailed он генерирует исключение, а getAllDirectories метод перехватывает и печатает вывод как:

Error Caught:java.nio.file.AccessDeniedException: file_path

Ошибка примерно такая:
