Adding lower restriction to Applet / Webstart

Question

I have a simple Applet application and my code creates ImageIcon objects from the same url from the Applet. When I run the application, I get a message about unrestricted access, it scares the user.

How I configure my Applet or my JNLP to only show specific restriction messages?

Edited After all, I refactor my code and find ways to load image correctly. To load image from JAR: http://docs.oracle.com/javase/tutorial/uiswing/components/applet.html#images. To load image from Applet: imageIcon = new ImageIcon(getImage(getCodeBase(), "image/image_name.png"));

Beyond the more specific permissions shown for the JNLP API services, Java does not offer any finer permission gradations than all-permissions, j2ee-application-client-permissions or sand-boxed (no security element).

However it seems this warning is seen due to a bug linked by the OP.
