Can't Set Value in JSpinner

Question

I am having trouble setting a value to a JSpinner in my code.
I am using two JSpinners, both with SpinnerNumberModels.
I use the Object JSpinner.getValue() method to get the current value from that JSpinner, change that object into an Integer format, and perform an arithmetic operation on the integer.
I then change the resulting integer into an Object format, and call the method JSpinner.setValue(Object).
The setValue method never changes the value of the JSpinner, and occasionally throws an IllegalArgumentException - depending on where I put it in the code.
The problem appears to come from either all the changing formats or the setValue method.
Any suggestions?

Perhaps this example will help?
import java.util.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
public class Dork extends JFrame implements ActionListener
     JSpinner dizzy;
     public static void main(String[] args)
          Dork dork=new Dork();
     public Dork()
          super("Dork");
          setDefaultCloseOperation(EXIT_ON_CLOSE);
          Container content=getContentPane();
          dizzy=new JSpinner(new SpinnerNumberModel(5,1,10,1));
          content.add(dizzy,BorderLayout.CENTER);
          JButton increment=new JButton("Increment");
          increment.addActionListener(this);
          content.add(increment,BorderLayout.SOUTH);
          pack();
          setLocationRelativeTo(null);
          show();
     public void actionPerformed(ActionEvent e)
          Integer value=(Integer)dizzy.getValue();
          Integer plusone=new Integer(value.intValue()+1);
          dizzy.setValue(plusone);
}
