Cannot Find MathUtils

When we look through the code in our WPILibj, and through some of the functions in Joystick, we can’t seem to find the MathUtils class in com.sun.squawk.util.MathUtils. I know from looking around ChiefDelphi that other teams don’t seem to be having this problem.

Is there some way I can find or get this class? When I’ve looked around for it, the ones that I find are definitely not the correct ones. Is there an update or something that I missed?
