should this comment just be removed entirely?

src/java.desktop/share/classes/java/awt/Toolkit.java line 1353:

src/java.desktop/share/classes/javax/swing/JComponent.java line 108:

> 106:  * whose root is a top-level Swing container.
> 107:  * Top-level Swing containers --
> 108:  * such as <code>JFrame</code>, <code>JDialog</code> --
