As a Java programmer and someone who learned how to program on an Apple //e, I think this is very cool. I was able to get it to work in jace.jar but not in AppleWin. There are a couple of additions that could make this much better: 1. A JIT or AOT compiler to speed up the run time. 2. The ability to utilize Apple //e RAM extenders to increase the amount of memory available to Java apps. For example, emulation of the RAMworks III card is supported by AppleWin and can extend the available RAM to 8MB. This is done with the " -r 127 " command line switch on AppleWin.
