Some more example for the integral:
Integrate[PolyLog[2, Exp[I*(x - y)]], {y, 0, 2*Pi}]
with x=5/2, I get 0 as expected. But with x=2.5 I get
19.634954084936204 + I*1.7763568394002505`*^-15
which is not close to zero! With x=-2.5 I get
44.964016795241896 + I*1.7763568394002505`*^-15
etc.
I have only one conclusion: there is a
bug with Integrate or PolyLog or both.
Any suggestion?
