Divide by zero when extra message is too long on indefinite progress bar

[rharder]

I'm using an indefinite progress bar, and if the setExtraMessage() value is too long, ProgressBar throws an Arithmetic exception for a divide by zero. It comes from DefaultProgressBarRenderer line 96:

int pos = (int)(progress.current % length);

An example:

public static void main(String[] args) throws InterruptedException {
    try (ProgressBar pb = new ProgressBar("test", -1)) {
        for (int i = 0; i < 10; i++) {
            pb.step();
            // May differ for your terminal...
            //                 Mine breaks and is "too long" when I get to 38: |
            // (At 37, it breaks when the counter goes double digits)
            pb.setExtraMessage(Paths.get("12345678901234567890123456789012345678").toString());
            TimeUnit.MILLISECONDS.sleep(250);
        }
    }
}

Stack trace looks like this;
