BoxLayout: problems

Question

I've a frame this default BorderLayout. Then I create this Panel:
JPanel rightPanel = new JPanel(new FlowLayout(FlowLayout.LEFT));and insert it into east of the frame:
frame.add(rightPanel, BorderLayout.EAST);Then I create a BoxLayout like this:
JPanel boxPanel = new JPanel();
boxPanel.setLayout(new BoxLayout(boxPanel,BoxLayout.Y_AXIS));And then insert 2 labels, a JComboBox and a JList into in:
boxPanel.add(yearLabel);
boxPanel.add(yearBox);
boxPanel.add(raceLabel);
boxPanel.add(scrollRaceListPanel);Then I adds the boxPanel into the rightPanel like this:
rightPanel.add(boxPanel);Here you see the result of it:

(notice the east-part)
As you see the labels are centered, and the ComboBox are getting the same width as the BoxPanel. I wan't the labels to have left align.
I hope somebody know why?

Well, I got another problem.
Here you see a example code:
import javax.swing.*;
import java.awt.*;
public class Main {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Test");     
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setResizable(false);
        JPanel rightPanel = new JPanel(new BorderLayout());
        JPanel rightCenterPanel = new JPanel(new FlowLayout(FlowLayout.LEFT));
        //creating rightTop-panel
        Box rightTopPanel = new Box(BoxLayout.Y_AXIS);
        JLabel yearLabel = new JLabel("�r:");  
        yearLabel.setAlignmentX(rightTopPanel.LEFT_ALIGNMENT);
        JComboBox yearBox = new JComboBox();
        yearBox.setAlignmentX(rightTopPanel.LEFT_ALIGNMENT);
        yearBox.setPreferredSize(new Dimension(100,20));
        rightTopPanel.add(yearLabel);
        rightTopPanel.add(yearBox);
        //creating rightCenter-panel       
        JList raceList = new JList();
        raceList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
        JScrollPane scrollRaceList = new JScrollPane(raceList);
        scrollRaceList.setPreferredSize(new Dimension(250,300));
        JPanel scrollRaceListPanel = new JPanel(new FlowLayout(FlowLayout.LEFT));
        scrollRaceListPanel.add(scrollRaceList);
        rightCenterPanel.add(scrollRaceListPanel);
        rightPanel.add(rightTopPanel, BorderLayout.NORTH);
        rightPanel.add(rightCenterPanel, BorderLayout.CENTER);
        frame.add(rightPanel, BorderLayout.EAST);
        frame.pack();    
        frame.setVisible(true);
}As you see, the ComboBox are getting full width. Why?
