Bug Description:
 
Throws exception when try to get the System Icon for root drives with
removable media.

   The drive names (roots) are retrieved properly. But it throws the
exception if the removable media does not exists. ex: if the CD Media
does not exists in the CD or DVD Drive, it will throw the exception.
Same with Floppy drive if the floppy does not exists, it will throw exception.

   If the floppy is in the floppy drive or CD is in the CD/DVD drive
the icons are shown properly.

   Here is the exception sample:

   Total root : 5
   Root : A: FileSystemView.getShellFolder: f=A: java.io.FileNotFoundException
at sun.awt.shell.ShellFolder.getShellFolder(ShellFolder.java:192)
at javax.swing.filechooser.FileSystemView.getShellFolder(FileSystemView.java:447)
at javax.swing.filechooser.FileSystemView.getSystemIcon(FileSystemView.java:182)
   at testjdk14.TestJFC.testForRoots(TestJFC.java:93)
at testjdk14.TestJFC.main(TestJFC.java:115)

   Root : C: Got icon.
   Root : D: Got icon.
   Root : E: FileSystemView.getShellFolder: f=E: java.io.FileNotFoundException
at sun.awt.shell.ShellFolder.getShellFolder(ShellFolder.java:192)
