apple.awt.fileDialogForDirectories property not working.

[Mike Swingler]

Sandboxing, by it's nature, prevents access to the user's general home directory. It restricts access to all but a very narrow per-app directory hidden within the user's home directory.

The viable alternative for the Swing API is to simply delegate to the AWT dialog (or a customized native dialog which better implements the Swing JFileChooser features) when run under sandboxing. A truly TCK compliant JFileChooser is simply not possible in the sandboxed environment - or at least in a form that will go anywhere interesting on the file system.
