Summary: Null File From OS X JFileChooser

Initial Comment:
Story:

A user opens a file.  The user forgets the file is open, and uses the open command.  The last openned file is already selected.  The user double-clicks on the file, wishing to open it again.  An exception is generated because the JFileChooser says the selected file is null.

Problem:

Mac OS X's implementation of JFileChooser isn't properly updating it's visual state when setSelectedFile(null) is called.  When the user double-clicks the already-selected file, the JFileChooser fails to update it's internal state to reflect the selection, leaving a null value where a File should be.

Fix:

setSelectedFile to any other File, then set it back to the old selection, then set it to null.  I used the File.getParentFile() for this purpose, but any old File should cause the JFileChooser to update.
