Question: double definite integral of...

I've stumbled across this double integral... int(int(2*x*sin(y),y),x); for which Maple can do it perfectly. However, if I specify the range for x and y, Maple will complain: int(int(2*x*sin(y),y=0..1),x0..1); Error, (in assuming) too many levels of recursion I'm just wondering if there is any other way around of evaluating this definite integral?
