For one, it appears you have an infinite loop in your code. Inside your jSpinner1StateChanged function, you are calling jSpinner1StateChanged(evt), which will cause an infinite loop.

How are you creating your JSpinner? If you're using ints, then create it by using a SpinnerNumberModel. This will simplify your code when getting the current value out of the spinner.

jSpinner1 = new JSpinner(new SpinnerNumberModel(0, 0, 30, 1));
Integer currentValue = (Integer)jSpinner1.getValue();
