To clarify, the error occurred when I hit the "upload" button, not when it was uploading, because it never got that far. That stacktrace indicates a java error in the IDE. Possibly in the oroinc library. Again, it didn't get to the compilation step.
As I modified the program, it got to a point where I could prevent the error if I removed an arbitrary chunk of code, but unfortunately I needed that code.
Here's another instance of the same problem http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1234031376
