Displaying an animated PNG (apng) using Swing?

Question

I'm trying to display an animated png (known as apng), by adding the image to a JLabel as usual. This works fine with normal gif-animations, however, I'd prefer to be able to support apng aswell.

I've been searching the net for existing frameworks or solutions for this, finding nothing. Has anyone else found a way to display animated pngs in Swing?

To understand why I want to implement apng, view the following example which demonstrates GIF's limitations: http://jsfiddle.net/RUX8w/ (your browser must support apng!)

A quick Google for "apng Java" turned up http://code.google.com/p/javapng and in particular, http://code.google.com/p/javapng/source/browse/trunk/javapng2/src/apng/com/sixlegs/png/AnimatedPngImage.java?r=300
