There is a typo at javadoc comments for
the java.awt.event.MouseEvent class:
--- Excerpt-from src/java/awt/event/MouseEvent.java ---
...
    /*
     * The mouse event's x absolute coordinate.
     * In a virtual device multi-screen environment in which the
     * desktop area could span multiple physical screen devices,
     * this coordinate is relative to the virtual coordinate system.
     * Otherwise, this coordinate is relative to the coordinate system
     * associated with the Component's GraphicsConfiguration.
     *
     * @serial
   */
    private int xAbs;

    /*
     * The mouse event's y absolute coordinate.
     * In a virtual device multi-screen environment in which the
     * desktop area could span multiple physical screen devices,
     * this coordinate is relative to the virtual coordinate system.
     * Otherwise, this coordinate is relative to the coordinate system
     * associated with the Component's GraphicsConfiguration.
     *
     * @serial
     */
    private int yAbs;
...

Due to using of
    /*
instead of
    /**
the Serialized Forms javadoc doesn't include these detailed javadoc comments.

Please correct the typos.
