  Bug 4284124 describes a problem with FlowLayout.preferredLayoutSize. The same
problem still exists in FlowLayout.minimumLayoutSize.

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

public class FixMe {
    public static void main(String[] args) {
        JFrame frame = new JFrame();
        JPanel panel = new JPanel();
        LayoutManager layout = new FlowLayout(FlowLayout.LEFT, 100, 0);
JButton b1 = new JButton("B1");
JButton b2 = new JButton("B2");
panel.add(b1);
panel.add(b2);
frame.getContentPane().add(panel);
frame.pack();
frame.setVisible(true);
b1.setVisible(false);
System.out.println(layout.minimumLayoutSize(panel));
b1.setVisible(true);
b2.setVisible(false);
System.out.println(layout.minimumLayoutSize(panel));
    }
}
