When I test any game on my site on OSX, I get errors like these. Linux and Windows work fine.
The games used to work before this computer had its Java version updated to 1.4.2_09. Is this a known issue or what?

#2

Yes it is a known issue, not specific to OS X. Using ImageIO to read compressed PNGs from a ZIP stream (compressed jar file) is broken in certain cases.

Probably related to bug #4764639 http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4764639

#3

There is a sticky thread in the Java2d section describing an easy workaround:

#4

Ahh it’s a different problem, I’m already loading my images that way.
