[9] Review request for 8168899 java.nio.file.InvalidPathException if click button in JFileChooser demo of SwingSet2

[Alexandr Scherbatiy]

Hello,

Could you review the fix:
  bug: https://bugs.openjdk.java.net/browse/JDK-8168899
  webrev: http://cr.openjdk.java.net/~alexsch/8168899/webrev.00
  It has been already discussed in the thread
http://mail.openjdk.java.net/pipermail/swing-dev/2016-October/006803.html

  However, the initial bug id 8167988 has been used for the original 
fix 7067885 reverting.
  The new bug id 8168899 has been created to fix both the original 
issue and the InvalidPathException.

 Thanks,
 Alexandr.
