I'd say upgrade your Java to Java 7, but I don't think the Apple-supplied JRE is up to 7 yet. In this case, you can get rid of the error by going to /config, open ModLoader.cfg in a text editor, and setting "mod_IC2AdvancedMachines" to off instead of on.

After installing that version of the JDK, you have to also configure your system so that it uses that interpreter first and foremost. To do that, you'll want to run the Java Preferences app, which lives in /Applications/Utilities. In that app, you'll see a list of all your Java installations. Drag the OpenJDK7 one to the very top.

Thread necro, no effort post, and a history of bad posting.
