The specification for java.awt.Container.addImpl(Component comp, Object constraints, int index) says:
"Throws:
    IllegalArgumentException - if comp has been added to the Container more than once".
Could you get an example which reproduces specified behavior?

Actually, if I try to add the Container more than once, then this part of specification takes effect:
" Note that if the component already exists in this container or a child of this container, it is removed from that container before being added to this container".
So, I can't understand how I can reproduce IllegalArgumentException.
