I finally managed to get the program to work properly. It turns out that ant was configured to
exclude all .java files in the src directory when performing the build. Instead -- on my machine,
it seems -- it would simply copy the .class files, put them in  the build folder, and be done with it.
I have no idea why this worked for Eric, or why eclipse did this at all.

After fixing this, I can see the elevators if the program runs. One-eighth of the time jvm
quits with an abnormal exit code of 134 before the program can display the main menu. A quick google
search is inconclusive. I'm guessing Nvidia drivers. Or Linux.
