When creating a JComboBox with both setEditable(true) and
setBorder(...TitledBorder...), the text area of the combobox
is resized to x2 the preferred size. This is related to one
half of bug 4412467, regarding only the Metal L&F.

Here's a program that demonstrates the problem, and the workaround.
The middle combobox is the buggy one.

-----------------
package bug;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class combobug extends JFrame {
    public static void main(String[] argv) {
        new combobug();
    }

    public combobug() {
        super("ComboBug");

        GridBagLayout gridbag = new GridBagLayout();
        GridBagConstraints con = new GridBagConstraints();
        JPanel holdAll = new JPanel(gridbag);

        con.fill = GridBagConstraints.NONE;

        String[] combo1Strings = { "This", "has", "no", "border" };
        JComboBox combo1 = new JComboBox(combo1Strings);
        combo1.setEditable(true);
        gridbag.setConstraints(combo1, con);
        holdAll.add(combo1);

        String[] combo2Strings = { "This", "has", "a titled", "border" };
        JComboBox combo2 = new JComboBox(combo2Strings);
        combo2.setEditable(true);
        combo2.setBorder(BorderFactory.createTitledBorder("Double Height"));
        gridbag.setConstraints(combo2, con);
        holdAll.add(combo2);

        String[] combo3Strings = { "This", "has", "a titled", "border",
                                   "and", "a holding", "JPanel" };
        JComboBox combo3 = new JComboBox(combo3Strings);
        combo3.setEditable(true);
        JPanel workaround = new JPanel();
        workaround.setBorder(BorderFactory.createTitledBorder("Workaround"));
        workaround.add(combo3);
        gridbag.setConstraints(workaround, con);
        holdAll.add(workaround);

        getContentPane().add(holdAll);
        pack();
        setVisible(true);

        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) { System.exit(0); }
        });
    }
}
