I've searched and found the following ticket:

https://josm.openstreetmap.de/ticket/5993

However, the fix for this ticket doesn't seem to be included or applicable to JMapViewer. I've since found the problem in code and am happy to supply a fix for JMapViewer, if not done already.

The following code fixes this problem in JMapViewer:

From BingAerialTileSource.java

{{{
    @Override
    public Image getAttributionImage() {
        try {
        	Image img=null;

        	InputStream is=getClass().getResourceAsStream(""images/bing_maps.png"");
        	
        	if (is!=null)
        		img=ImageIO.read(is);
        	
            	return img;
        	
		//Old Way encounters exception inline
        	//return ImageIO.read(getClass().getResourceAsStream(""images/bing_maps.png""));
        } catch (IOException e) {
            return null;
        }
    }
}}}
