“this” reference escaping during construction?

I would like to know whether leaking this in constructor issue is applied on this instance, since i believe the constructor has to invoke setJMenuBar() method to finish its construction, here is class implementation:

public class StaffManagerMainWindow extends JFrame implements ActionListener {

    public StaffManagerMainWindow(String title, Image icon) throws HeadlessException {
        ...
        setJMenuBar();
    }

    private void setJMenuBar() {
        ...
        exitItem.addActionListener(this);
        ...
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        throw new UnsupportedOperationException("Not supported yet.");
    }
}

I think there is a leak in the constructor. You are passing “this” before the complete initiallization of the object.
