SYNOPSIS
--------
IOException when dragging certain items from a JFileChooser into Windows Explorer

OPERATING SYSTEM
----------------
Reported on Windows Server 2008 SP1 and R2.
Possibly other Windows version.

FULL JDK VERSION
----------------
JDK 7 (tested with b143)
Java 6 (tested with 1.6.0_25)

REPRODUCTION INSTRUCTIONS
-------------------------
1. Compile and run the attached testcase
2. Navigate to "My Network Places" in the file list
3. Open a Windows Explorer window, and navigate to a temporary folder
   (any folder will do)
4. Drag an item from "My Network Places" in the JFileChooser and drop it
   into the Windows Explorer window

(NOTE: Dragging from the "Libraries" location exposes the same issue.)

Expected behaviour:
Item should be copied, as it is when dragging/dropping between two native Explorer windows

Actual behaviour:
Item is not copied, and an IOException is printed on the console:
