I was considering reporting this as a bug or feature but i thought i'd run it by the forum first and get some feedback.

This i the code i have

public class test {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		SpinnerNumberModel spinner = new SpinnerNumberModel();
		spinner.setValue(0);
		spinner.setStepSize(0.000001);
		System.out.println(spinner.getNumber());
		System.out.println(spinner.getNextValue());
		
	}

}

And the ouput is

0
0

Now if i'm not mistaken 0 + 0.000001 = 0.000001 not 0

So if the spinners value is either not previously set, or set to 0. no matter what the step size is it will not increment.
I believe if it is null it should consider that 0 or if 0 is set it should increment.
