The JFileChooser in Swing (Java 1.6.0_u25) doesn't seem to know how to deal with NTFS Junction Points or Symbolic Links.
The file chooser has no special handling:
int rv = mainfileChooser.showOpenDialog(parentFrame)
When using this on a Windows 7 box, the special folders under My Documents (My Pictures, My Videos, My Music) can't be entered - the user clicks on them, but nothing happens and they can't be selected. After some experimentation, the same thing happens with any SymLink or Junction Point (both pre-generated by the OS and manually created.)
.lnk Shortcuts to directories work fine.
Is there a way to fix this and let my users save images in "My Pictures"?
By an amazing coincidence, Java 1.6u27 just shipped, and includes a fix for this very issue!

The bug discussion revolves around DFS links, rather than Junction points, but I believe the issues are the same, and testing this locally all the wacky behavior has gone away and I can save to My Pictures (and friends) just fine.
