How to access network paths from Java on OSX?

Question

I try to access a network folder / UNC path from Java on Mac OSX. On Windows, the following test program works fine (at least one of the tested paths):

public class PathTest {
    public static void main(String[] args) {

        for (String path : Arrays.asList(
                "\\\\myserver\\transfer", "//myserver/transfer", "file://myserver/transfer", "smb://myserver/transfer")) {

            File f = new File(path);
            System.out.println(path + ": " + f.getAbsolutePath() + ", " + f.exists());

            Path p = Paths.get(path);
            System.out.println(path + ": " + p.toAbsolutePath() + ", " + Files.exists(p));
        }
    }
}

on Mac OS it fails to reach the folders:

\\myserver\transfer: /Users/tim/IdeaProjects/PathTest/\\myserver\transfer, false
//myserver/transfer: /myserver/transfer, false
file://myserver/transfer: /Users/tim/IdeaProjects/PathTest/file://myserver/transfer, false
smb://myserver/transfer: /Users/tim/IdeaProjects/PathTest/smb://myserver/transfer, false

When I use Finder, I can access the Folder (using the Guest user), by using "smb://myserver/transfer". What's wrong?

EDIT added NIO.2 test

Either mount the partition and access it as any local directory or use a specialized library such as JCIFS or Apache Commons VFS.
