3205patriots is an unknown quantity at this point
Robot class cannot be instantiated

My Robot class was initially creating an error when it was instantiated. I cannot find the error anymore, but it was the exact same one previously posted on chief delphi, but there was no solution.

ERROR Unhandled exception instantiating robot org.usfirst.frc.team3205.robot.Robot java.lang.ExceptionInInitializerError at [java.lang.Class.forName0(Native Method), java.lang.Class.forName(Class.java:259), edu.wpi.first.wpilibj.RobotBase.main(RobotBase.jav a:197)]

My greatest confusion is that the driver station is now outputting nothing at all for this project, but will output for other projects that work.


Here is our Robot class:
