JDK-8213583 - Error while opening the JFileChooser when desktop contains shortcuts pointing to deleted files
Description
A DESCRIPTION OF THE PROBLEM :
If the user's desktop directory is missing in Windows 10, JFileChooser throws an exception and can not be used.

When the desktop directory is not present, the file chooser should recover gracefully and still be usable.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a new user on Windows 10.
Use Windows Explorer to delete the new user's desktop directory (stay logged in else the desktop directory will be recreated).
Compile and run the code.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expect a usable file chooser without "Desktop" in the "Look in" list.
ACTUAL -
The file chooser does not pop up and these exceptions are displayed:

Additional Information from submitter: ============================= The exceptions in the report are from OpenJDK 15.0.2. I also tested with OpenJDK 15.0.1 and found the same. Occasionally we have users with some sort of system directory problem - missing, inaccessible, etc. so we do encounter this and similar problems in practice.
