The com.sun.java.swing.JTabbedPane.insertTab(..) does not work properly in JDK1.2-beta4.
The example works properly under JDK1.2Beta3N but does not work under JDK1.2Beta4H:
------------------------------8-<--------------------------------------------
import com.sun.java.swing.JTabbedPane; // Warning: Do not forget to replace "com.sun.java.swing"
import com.sun.java.swing.Icon; // to "java.awt.swing" to test under former builds of JDK

public class Test {
 public static void main(String s[]) {
    
 String name = "Canvas";
 StubIcon icon = new StubIcon();
 JTabbedPane c = new JTabbedPane();
 java.awt.Component comp = new java.awt.Canvas();

 c.addTab("Checkbox",new java.awt.Checkbox()); // Add the couple of objects
 c.addTab(name,comp);

 c.insertTab("Choice",null,new java.awt.Choice(),"tip",0); //Insert at 0 position
 c.insertTab(name,icon,comp,"tip",1); //Insert at 1 position
 
 if (!( c.getTitleAt(1).equals(name) && c.getIconAt(1)==icon
                         &&
               c.getComponentAt(1)==comp )) {
         System.out.println("The JTabbedPane "+c);
         System.out.println("The icon on 1 position is "+c.getIconAt(1)+
                            " must be "+icon);
         System.out.println("The component is "+c.getComponentAt(1)+
                            " must be "+comp);
         System.out.println("The name is "+c.getTitleAt(1)+
                            " must be "+name);
         System.exit(0);
 }
  System.out.println("OKAY");
  System.exit(0);
  }
}
class StubIcon implements Icon {
 public void paintIcon(java.awt.Component c, java.awt.Graphics g, int x,
                          int y) {}
 public int getIconWidth() {return 0;}
 public int getIconHeight() {return 0;}
}
