Bypass forced JOptionPane

I am using a scripting API for making a script for a bot for a game I play, however whenever I override a bot manager, a JOptionPane appears that blocks execution until I close it, however I would like to run this script without human intervention, so I would like to bypass this pane.

I have tried to overwrite the JOptionPane class at runtime to no avail, and I have tried contacting the developer of the bot's API to add an override however he doesn't want to add an override.

I am open to any methods of resolving this (reflection, etc.), I was thinking of detecting the pane's title and force-closing it however that it way beyond my skill level.

Pane title: Override Warning!
I would add the pane text however it reveals personal information.

Here is the possibility to suppress all JOptionPane dialogs. If you want to do it with some of them you probably need to provide additional check for dialog title.

import java.awt.AWTEvent;
import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.FlowLayout;
import java.awt.Toolkit;
import java.awt.event.AWTEventListener;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowEvent;

import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import javax.swing.WindowConstants;

public class CloseDialog implements Runnable {

    private final AWTEventListener hideOptionPaneListener = new AWTEventListener() {

        @Override
        public void eventDispatched(AWTEvent event) {
            if (event instanceof WindowEvent) {
                processWindowEvent((WindowEvent) event);
            }
        }
    };

    private void processWindowEvent(WindowEvent we) {
        if (we.getID() == WindowEvent.WINDOW_OPENED && we.getWindow() instanceof JDialog) {
            final JDialog dlg = (JDialog) we.getWindow();
            Component[] comps = dlg.getContentPane().getComponents();
            if (comps.length > 0 && comps[0] instanceof JOptionPane) { // probably also check dialog title
                dlg.setVisible(false);
            }
        }
    }

    @Override
    public void run() {
        final JFrame frm = new JFrame("Test frame");
        JButton button = new JButton("Show option pane");
        button.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                JOptionPane.showMessageDialog(frm, "Simple message");
            }
        });
        final JCheckBox checkBox = new JCheckBox("Suppress option pane");
        checkBox.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                if (checkBox.isSelected()) {
                    Toolkit.getDefaultToolkit().addAWTEventListener(hideOptionPaneListener, AWTEvent.WINDOW_EVENT_MASK);
                } else {
                    Toolkit.getDefaultToolkit().removeAWTEventListener(hideOptionPaneListener);
                }
            }
        });
        JPanel top = new JPanel(new FlowLayout());
        top.add(button);
        frm.add(top, BorderLayout.NORTH);
        frm.add(checkBox, BorderLayout.SOUTH);
        frm.setSize(400, 200);
        frm.setLocationRelativeTo(null);
        frm.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frm.setVisible(true);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new CloseDialog());
    }
}
