If it is written as
Sum[Cos[x*Pi], {x, 0, Infinity}]
Mathematica concludes that the sum does not converge.

I think that the sum does not converge. Does
the following (from Mathematica for Students,
v. 4.0.1) reveal a bug? If so, do you have
any insight into this bug?
In[1]:= Sum[Cos[x], {x, 0, Infinity, Pi}]
Out[1]= 1/2
