JFileChooser returns an incorrct path for "My Computer","NetworkNeighbourhood" on windows.
 
On WinXp, open the FileChooser select a file (say Test.java) from a c:\ drive or any other folder in it, then move the file view upto MyComputer. Now click on Open -
Observed
The file name in the subsequent message dialogue is shown as "0x11\Test.java"
Expected
The file name in the subsequent message dialogue should show as "My Computer:\Test.java"
If you try this with Network Neighborhood it shows up as "0x12\Test.java.
I was able to trace this back right upto tiget b32d build.
