Peacekeeper - The Browser Benchmark from Futuremark Corporation

I don't have Java installed in my systems and was able to run the benchmark with other browsers (Opera 9.64, Chrome 1.0.154.65, Firefox 3.0.10 and IE8). but, I can't run the benchmark with Safari 3.2.3 because it claims that it requires Java.

what's wrong???
