A DESCRIPTION OF THE PROBLEM :
Hi,

The java.awt.Desktop class does not allow to open a network file with blank character into the path. For example, it fails to open "//serverName/drive/Temp/my folder/a simple file.xxx", where xxx may be any extension : txt, pdf...

For information, it works if the path contains the drive letter "N:/Temp/my folder/a simple file.txt", or if the path does not contain any blank like "//serverName/drive/Temp/my_folder/a_simple_file.txt".


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Should open the file with the application used for its extension, like Notepad for txt file.
ACTUAL -
IOException

ERROR MESSAGES/STACK TRACES THAT OCCUR :
The ouput is:

java.io.IOException: Failed to open file:////serverName/drive/Temp/my%20folder/a%20simple%20file.txt. Error message: Le chemin d'accès spécifié est introuvable.
        at sun.awt.windows.WDesktopPeer.ShellExecute(Unknown Source)
        at sun.awt.windows.WDesktopPeer.open(Unknown Source)
        at java.awt.Desktop.open(Unknown Source)
        at Swing.myDesktop.main(jvDesktop.java:26)



REPRODUCIBILITY :
This bug can be reproduced always.
