Layout centering issue with BoxLayout

Question

The code is two BoxLayout panels placed in a frame with FlowLayout.
I cannot get the second panel's label to be centered. I purposely made both panels identical. Any ideas what I am missing?
import java.awt.*;
import javax.swing.*;
public class MVCtest extends JFrame {
     public MVCtest() {
          getContentPane().setLayout(new FlowLayout());
          JTextField controller = new JTextField(10);          
          JLabel controllerLabel = new JLabel("Controller");
          JPanel controllerPanel = new JPanel();
          controllerPanel.setLayout(new BoxLayout(controllerPanel, BoxLayout.Y_AXIS));
          controllerPanel.setBorder(BorderFactory.createEtchedBorder());
          controllerPanel.add(controllerLabel);
          controllerLabel.setAlignmentX(controllerLabel.CENTER_ALIGNMENT);
          controllerPanel.add(Box.createVerticalStrut(10));
          controllerPanel.add(controller);
          JTextField view = new JTextField(10);     
          JLabel viewLabel = new JLabel("Controller");
          JPanel viewPanel = new JPanel();
          viewPanel.setLayout(new BoxLayout(viewPanel, BoxLayout.Y_AXIS));
          viewPanel.setBorder(BorderFactory.createEtchedBorder());
          viewPanel.add(viewLabel);
          viewPanel.setAlignmentX(viewLabel.CENTER_ALIGNMENT);
          viewPanel.add(Box.createVerticalStrut(10));
          viewPanel.add(view);
          getContentPane().add(controllerPanel);
          getContentPane().add(viewPanel);
     public static void main(String[] args) {
          JFrame.setDefaultLookAndFeelDecorated(true);
          MVCtest frame = new MVCtest();
          frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);
          frame.setSize(400,400);
          frame.setVisible(true);
}Thanks,

Problem solved, yet not understood.
I posted the question and now eliminated the issue.
I simply cut and pasted the first panel code over the second panel's code. I then renamed the variables and the problem went away.
I don't know why because I didn't see any problem with the first code.
Thanks to any and all who committed brain power to this problem.
