I have a SplitPane, where the right component is a tabbed pane, and each tab is a JInternalFrame. This JInternalFrame holds the AWT Panel (this panel is needed for my application to communicate other JNI calls using a native handle). I have a continuous layout set to false in Splitpane UI. Now, when I slide the split pane divider, it goes behind the AWT panel. How to fix this z-order issue.

Please refer the following image that I have attached. enter image description here

Now I am attaching the code.

import javax.swing.*;
import javax.swing.plaf.basic.BasicSplitPaneDivider;
import javax.swing.plaf.basic.BasicSplitPaneUI;
import java.awt.*;

public class SplitPaneExample {

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            JFrame frame = new JFrame("SplitPane Example");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setSize(800, 600);

            // Create left component
            JPanel leftPanel = new JPanel();
            leftPanel.add(new JLabel("Left Component"));

            // Create right component
            JTabbedPane tabbedPane = new JTabbedPane();
            JInternalFrame internalFrame = new JInternalFrame("Internal Frame", true, true, true, true);
            internalFrame.setSize(400, 300);
            internalFrame.setVisible(true);

            // Create a layered pane to manage z-order
            // Create the AWT Panel
            Panel awtPanel = new Panel();
            awtPanel.setBackground(Color.CYAN);
            awtPanel.add(new Label("AWT Panel inside JInternalFrame"));

            // Add AWT Panel to internal frame
            internalFrame.add(awtPanel);
            internalFrame.pack();
            internalFrame.setVisible(true);

            // Add internal frame to tabbed pane
            tabbedPane.addTab("Tab 1", internalFrame);

            // Create SplitPane
            JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, leftPanel, tabbedPane);
            splitPane.setDividerLocation(200);
            // Add splitPane to layeredPane

            frame.add(splitPane);
            frame.setVisible(true);
        });
    }
}

I have tried using JLayeredPane to hold the splitpane/ tabbedpane/ Awt panel... but nothing worked.

Any suggestions or workaround is highly appreciated. Any suggestions on alternate way to get handle for JNI in this hierarchy is also highly appreciated.
