Details:

When calling ImageIO.read() with an URL instance the call fails with this
exception:

java.lang.IllegalArgumentException: extension is null
   at gnu.java.awt.peer.gtk.GdkPixbufDecoder.findFormatName
(GdkPixbufDecoder.java:302)
   at gnu.java.awt.peer.gtk.GdkPixbufDecoder$GdkPixbufReader.<init>
(GdkPixbufDecoder.java:507)

(GdkPixbufDecoder.java:417)
   at javax.imageio.spi.ImageReaderSpi.createReaderInstance
(ImageReaderSpi.java:98)

   at javax.imageio.ImageIO.read (ImageIO.java:590)
   at org.kicksass.freefodder.ffmki.ResourceLoader.loadImage
(ResourceLoader.java:88)

The official documentation for
javax.imageio.spi.ImageReaderSpi.createReaderInstance says that the 'ext'
argument may be null. In the above example a png was tried to read.
