Working code fails to "check". Why?

It works fine locally. Why is the online tester failing this code?

Can you provide the code?

You may be doing too much. I removed the try catch block and it passed.

public void drive(int laps) {
    if (!(laps > barCount)) {
        lapsDriven += laps;
        barCount -= laps;
    } else {
         throw new IllegalArgumentException("Not enough fuel to drive " + String.valueOf(laps) + " more laps");
    }
}

Well paint my britches! That's dumb. Who ever heard of doing too much work getting one into trouble. LOL. Thanks.

Still think it should have passed.
