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!)

There doesn't seem to be much support for APNG in Java at the moment. Most examples I found required you to physically read the file yourself, which is a lot of additional overhead... — MadProgrammer, Mar 12 '13 at 23:02
'The way' would be to add an SPI for APNG to the run-time class-path of the app. Given the comment of @leonbloy though, I doubt you will find an existing SPI. — Andrew Thompson, Mar 13 '13 at 00:52
@leonbloy I understand that. You don't know of any "API" which implements it anyway? — Zar, Mar 13 '13 at 01:15
@Zar: No, I've been looking into it (perhaps to include support in my PNGJ library), but frankly I disliked its approach. But there might exist other libraries. — leonbloy, Mar 13 '13 at 01:34
@leonbloy Hmm, okay. I'll keep on looking. Thanks for your input. — Zar, Mar 13 '13 at 11:03
@AndrewThompson Thought so as well, sadly. Thanks anyways, though. — Zar, Mar 13 '13 at 11:05

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
