AccessControlException on changing the window icon in an unsigned application

If you attempt to change the icon of the Stage in an unsigned application, it throws an AccessControlException. This will cause the entire application to hang on startup.

Here is a very simple example to reproduce this:
Stage {
    width: 640
    height: 360
    title: "Shelf Test"
    icons: Image {
        url: "http://jfxtras.org/portal/webdav/liferay.com/guest/document_library/Samples/JFXtrasDemo/JFXtrasShelf/images/image%%20(9).jpg"
    }
}
(you will need to modify the url to be an image on the same server)

And here is the associated stack trace (fixed):

The only workaround is to not use Stage icons.
