Setting the first JComboBox item to null results
in a bad computation of the height for the following
items. I was really expecting the null string "" to
behave like a space string " ". Here's a sample
to duplicate the problem.

----------------- cut here ----------------
//
// Test case for JComboBox. Setting a null string "" results in an
// inaccurate combo item height computation.

import com.sun.java.swing.*;
import java.awt.*;
import java.awt.event.*;


public class Test extends JFrame
{
	
	public Test()
	{
		setTitle("JComboBox test");
		setLocation(400, 100);
		setSize(300, 200);
		addWindowListener(new WindowAdapter() {
			public void windowClosing(WindowEvent e) {System.exit(0);}
			});
		
		Container c = getContentPane();
		c.setLayout(new GridLayout(5,1));
		c.setBackground(Color.lightGray);

		JComboBox combo = new JComboBox();
		combo.addItem("");				// This is causing the problem
		combo.addItem("Second");
		combo.addItem("Third");
		c.add(combo);
	}
		
	public static void main(String args[])
	{
		Test test = new Test();

		try {
			UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
		}
		catch (Exception e) {
			e.printStackTrace();
		}
		test.show();
	}
}
