Drag and Drop of Files in Mac does not work as expected (if swing is used, too).

The file MainFXOnly contains a simple Drag and Drop example that is based on FX Controls only (that means, no swing). The output of the program is as expected, a list of DRAG_OVER entries and later one entry that indicates that I dropped the file.

java.runtime.version: 1.7.0_06-b23
javafx.runtime.version: 2.2.0-beta-b19
===== DRAG_OVER =====
system mode: COPY
source modes: [COPY, MOVE, LINK]
[... multiple DRAG_OVER events ...]
handle drag dropped: TableView[id=null, styleClass=table-view]
has files: true
files: [/Users/phe/Desktop/test]
content types: [[application/x-java-file-list, java.file-list]]

The problem now occurs if I try to use Swing and FX together (MainFXWithSwing.java). I tried to have as least differences between the two versions as possible, and I hope I started FX inside of Swing correctly. But if I use FX as it is supposed to be used in Swing, then there is a bug in the drag and drop management:

java.runtime.version: 1.7.0_06-b23
javafx.runtime.version: 2.2.0-beta-b19
===== DRAG_OVER =====
system mode: MOVE
source modes: [COPY, MOVE, LINK]
handle drag dropped: TableView[id=null, styleClass=table-view]
has files: false <----------- I dropped a file, as before, why is the boolean flag false, here?
files: []
content types: []
