A DESCRIPTION OF THE PROBLEM :
private void dropFile( DropTargetDropEvent event, Transferable transferable ){
event.acceptDrop( DnDConstants.ACTION_COPY );
@SuppressWarnings("unchecked")
List<File> dropppedFiles = (List<File>) transferable.getTransferData( DataFlavor.javaFileListFlavor );
// left out code
}

On getTransferData() following exception is thrown:
Exception in thread "AWT-EventQueue-0" java.awt.dnd.InvalidDnDOperationException: data translation failed
