Drag n Drop of javaFileListFlavor fails to drop the files properly when dragged and dropped across JVMs. This works fine within same JVM.

Also it works fine if we enable X11 Toolkit setting awt.toolkit=sun.awt.X11.XToolkit property.

Compile and two instances of attached FileListDnDTest
Drag from source list and drop in target list, the entries of both the list must be same. Now Drag from source list of one Frame and drop it to target list of another Frame. The target list must show second element repeated.
Refer to attached screenshot.

If the same steps are followed with awt.toolkit=sun.awt.X11.XToolkit property, everything works fine.
