<Swing Dev> RFR: 8272148: JDesktopPane:getComponentCount() returns one extra than expected with GTKLookAndFeel [v2]

[Pankaj Bansal]

> A container may include few default components as children, which are added to it during creation. Due to this, calling function getChildrenCount on a new created instance may return non zero value. This behaviour may vary according to L&F also, as some L&F may add some default components to a container, but other L&F may choose not to do so.
> 
> The current bugs reports that this behaviour looks suspicious as it is expected that a newly created container will have zero  children.
> 
> Current specification is not clear on this whether it is allowed for a container to contain default components or not. The fix make changes to the specification to clarify the same.
> 
> Note: I think this will need a CSR, I will file one after the review is completed
