Yeah, I see the point. Another option is to make the field private, create a final package-private getter (though why? we have a lovely public one already), and private setter. The setter would be invoked through the sun.awt.AWTAccessor by the toplevel window whenever its own GC gets changed (holding the TreeLock and traversing the whole hierarchy). It will also be assigned when adding a component to a container (by using the container's local copy of the gc - which we assume correct). This way we ensure there's only one value of gc in every single component in the given toplevel window at any moment of time. I guess changing the GC is not quite frequent operation to worry much about the performance of this approach?
By the way, Canvases may be created with a non-default GC. How should these be treated then if we think we should have the same GC for every component in a Window?
