Thanks, I guess this should motivate me to describe the dominator tree and it's advantages in more detail in a follow up post :) Regards, Markus

Very interesting article. I have written on the difficulty to measure an object graph size, applied to the HttpSession. Shameless plug: a good tool to measure your HttpSession sizes is MessAdmin (open-source, production-ready). It does much more than that of course, but that would get out of the scope of this article!
