PNG Error when exporting Jar for OSX

Question

I am using LWJGL, and Slick to load in my Images. I exported my jar and created a fat jar using JarSplice with the dependencies for Windows and OSX. The jar runs perfectly on windows however on OSX I am getting the following error referring to my PNG assets.

java.io.IOException: unsupported interlace method

I've resaved all my assets and re-exported without interlacing, so I don't know what the problem is.

All help appreciated, thanks!
