Drag and Drop - Swing Compatibility

I'm porting my mixed Swing/JavaFX app to full JavaFX.  One thing I can do in the application is drag an object from a JTree and drop it into my Scene.

Swing allows me to have an arbitrary Java Object as the data in the Transferrable.  When dropped this shows up in a DragBoard with MIME type "application/x-java-serialized-object" with the object instance as the data.  The drop proceeds fine.

Here's the catch.  The data object is NOT serializable.  When I try to create the equivalent DragBoard from the JavaFX side it throws an exception saying as much as soon as I call setContent on the DragBoard.

How did Swing manage to create the DragBoard? Can I do the same?
