Hi Rémi, As we can see, operandStack.pop() is commented, so the code will not take effect ;)
Jochen told me some operands left in the stack, I should have pop them by myself, currently framework pops them for me automatically... so I tried operandStack.pop(), but I got AIOOBE because stack is empty...
