The Choice component is much taller than it claims to be. The preferred size is 21 pixels, so layout managers treat it as such and set the compoent's bounds accordingly but when the peer is created it's closer to 28 pixels high. This results in clipping and overlapping components when positioned by most layout managers.

The problem seems to have been introduced in the peer code by a fix requested by Netscape.

The following example illustrates the problem using GridBagLayout:

-- CUT HERE --
import java.awt.*;

public class ChoiceFrame extends Frame {
  public static void main(String args[]) {
    Frame f = new ChoiceFrame();
    GridBagConstraints gbc = new GridBagConstraints();

    f.setLayout(new GridBagLayout());
    gbc.gridy = 1;
    f.add(new Button("I shouldn't be overlapping!"), gbc);
    gbc.gridy = 0;
    f.add(new Choice(), gbc);
    f.pack();
    f.show();
  }
}
