JOptionPane getting it's icon

Question

I have created a JOptionPane and I am trying to get it's icon. I read that the icon was driven by the message type so why is the icon null? Better yet, how can I get get the error icon that it uses. That's my goal. This is what I have done
String message = "msg";
JOptionPane pane = new JOptionPane(message, JOptionPane.ERROR_MESSAGE);
JDialog dlg = pane.createDialog(null, "title");
Icon icon = pane.getIcon();
//the Icon is null  BOOOO 
//if I add do this then the icon shows up... uhm... icon is bound in the show.  How is does show get it?
dlg.show();

you can use :
UIManager.getIcon("OptionPane.questionIcon")
UIManager.getIcon("OptionPane.errorIcon")
UIManager.getIcon("OptionPane.informationIcon")
UIManager.getIcon("OptionPane.warningIcon")
