'Don't' reach it, but simply wait for the result returned
by the JOptionPane. E.G.

<sscce>
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

class DisappearingDialog {

  public static void main(String[] args) {
    Runnable r = new Runnable() {
      public void run() {
        JFrame f = new JFrame( "Disappearing Dialog" );
        f.getContentPane().add(
          new JLabel("JFrame", SwingConstants.CENTER) );
        f.setMinimumSize( new Dimension(400,300) );
        f.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );

        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);

        final JDialog dialog = new JDialog(f, "The Dialog");
        JButton openOpt = new JButton("Show Option Pane");
        openOpt.addActionListener( new ActionListener(){
            public void actionPerformed(ActionEvent ae) {
              int result = JOptionPane.showConfirmDialog(
                dialog,
                "Close the Dialog?");
              if (result==JOptionPane.OK_OPTION) {
                dialog.setVisible(false);
              }
            }
          } );
        dialog.getContentPane().add( openOpt );
        dialog.pack();
        dialog.setLocationRelativeTo( f );
        dialog.setVisible( true );
      }
    };
    EventQueue.invokeLater(r);
  }
}
