import javax.swing.JComboBox;

public class Main {
  public static void main(String[] args) {
    JComboBox<String> emptyBox = new JComboBox<String>();
    emptyBox.addActionListener(new ActionListener() {
      @Override
      public void actionPerformed(ActionEvent e) {
        Thread.dumpStack();
      }
    });
    emptyBox.addItem("test");
