There is one problem at the moment:

Ordering of layers is different in cocoa versus swing.

Under cocoa the first layer stays visually on top while the latest is  
active.
Somewhat counter-intuitive.

Under swing visually it's the same, but the first created layer is  
active.

Actually, from my P.O.V. , the _latest_ built view could be on top  
_and_ be active.

A.T.M. one has to build the views again in a different order for this
(functions are convenient -- just switching focus on existing views  
wouldn't work here).
It is just a little more complicated with the different behaviours in  
SwingOSC and Cocoa.
