Hi Dan,
I've seen that you have introduce a common super interface for entry and 
tree node,
I suppose that  you check that there is no performance regression.
I wonder if an abstract class is not better than an interface because as 
far as I know
CHA implemented in hotspot doesn't work on interface
(but I may be wrong, there is perhaps a special optimization for arrays).
