Just to revive the discussion...

I guess you mean an overridden JComponent.invalidate() here, since 
revalidate() calls this method to invalidate the component hierarchy.

As we understand from the previous discussions, the root problem is 
indeed the AWT's invalidate() method that goes too far doing its job. 
Since Swing introduces the concept of "validate root", it seems really 
natural to me to override the JComponent.invalidate() method 
accordingly. At least I can't imagine a problem caused by choosing this way.

What do Swing people think about that?
