FULL PRODUCT VERSION :
java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Windows 7 64-bit

EXTRA RELEVANT SYSTEM CONFIGURATION :
Microsoft Outlook Professional Plus

A DESCRIPTION OF THE PROBLEM :
I am trying to implement a requirement to drag and drop documents attached in an email into a JavaFX 8 application running on jdk 8b45. I am able to drag and drop from any Windows folder on my computer but not from an Outlook email attachment.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Drag a file from Windows folder onto FX application. This works.
2. Now drag an attachment from Microsoft Outlook email. This does NOT work.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Should be able to drag and drop attachments from Outlook emails.
ACTUAL -
Does not identify the files being dragged from an email attachment.

For email attachments, "dragboard.hasFiles()::false" is always displayed on the console inside 'setOnDragOver' method.

REPRODUCIBILITY :
This bug can be reproduced always.
