Re: AP Computer Science

It's a problem with graphics and hardware acceleration. In 1.3 with hardware acceleration turned off, the case study graphics work. In 1.4.1, where you can't turn off hardware acceleration, or 1.3 with hardware acceleration on, the graphics don't work.

It has to be proven that Apple is guilty :-) in your case.

that's possible that there is a programmer mistakes (bugs) in a Case Study

in many cases as I saw many so called Apple's Java bugs were results of poor java programming
there are situations when java doesn't promise certain behaviour (in many cases it's a threading problem)
and windows programmer think that if their java programs run smoothly on windows then they
will run fine on any other platform. that assumption is wrong.

besides from your message I couldn't understand what kind of the problem Case Study has
how it looks like ? etc

The AP Computer Science curriculum uses Java and includes a Case Study which implements a graphical simulation of fish in an enclosed tank.

The problem is that the OS X version of Java doesn't correctly deal with the graphics in the Case Study, so all of the high school kids who take AP Computer Science and run the program on a Mac will, correctly at this point, assume that Apple's Java implementation is sub-par. That's a few thousand students who are likely to go on to major in Computer Science in college, and will be prejudiced against Macs because of a bad experience.

The problems have to get fixed, and they have to get fixed in Jaguar, because schools may not be able to afford to upgrade to Panther. Please. It's already the case that my state has adopted school administration software that won't run on Macs, so it's likely that no teacher will get a Mac on their desktop, because they can't take attendance, etc., on them.
