Hyperlink in JEditorPane not opening on MAC

I have a JEditorPane, showing in a JOptionPane, with an URL I want to open before closing my application. It works well on Windows and Linux, but it doesn't work on Mac.

Here is the code :

//LINK
String link = "http://www.google.com/";
String link_name = "Google";

//Editor_Pane
JEditorPane editor_pane = new JEditorPane();
editor_pane.setEditorKit(JEditorPane.createEditorKitForContentType("text/html"));
editor_pane.setText( /*some text*/ + "<a href=\"" + link + "\">" + link_name + "</a>");
editor_pane.setEditable(false);

//ADD A LISTENER
editor_pane.addHyperlinkListener(new HyperlinkListener(){
public void hyperlinkUpdate(HyperlinkEvent e){
if(e.getEventType() == (HyperlinkEvent.EventType.ACTIVATED)){

//OPEN THE LINK
try{ Desktop.getDesktop().browse(e.getURL().toURI());
}catch (IOException | URISyntaxException e1) {e1.printStackTrace();}

//EXIT
System.exit(0);
}
}
});

//SHOW THE PANE
JOptionPane.showOptionDialog(null, editor_pane, "text", JOptionPane.DEFAULT_OPTION,
JOptionPane.PLAIN_MESSAGE, null, new Object[] {}, null);


The link seems clickable, but nothing happens when I click, even if I try to remove the
Desktop.browse
method and let only the
exit
method.

What am I doing wrong ? Thanks !

Answer

Try adding:

editor_pane.setEditable(false);

The pane needs to be readonly for links to be clickable. See JEditorPane for more details:

The HTML EditorKit will generate hyperlink events if the JEditorPane is not editable (JEditorPane.setEditable(false); has been called).

EDIT:

import java.awt.Cursor;

public class TestLink {

    public static void main(String[] args) {
        JLabel label = new JLabel("stackoverflow");
        label.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));

        label.addMouseListener(new MouseAdapter() {  
            public void mouseClicked(MouseEvent e) {  
                if (Desktop.isDesktopSupported()) {
                    try {
                      Desktop.getDesktop().browse(new URI("http://stackoverflow.com"));
                    } catch (Exception ex) {
                        ex.printStackTrace();
                    }
                  } else { 
                      //TODO 
                  }
            }  
        }); 
        JOptionPane.showMessageDialog(null, label);
    }
}
