Why can't Mathematica do this simple integral ?

Hi
        I have been trying to integrate the following :

        Integrate[Cosh[2 Abs[x-y]] 2 y, {y,0,1/2},
  Assumptions->{Im[x]==0,x>0}]

        However, Mathematica chokes and simply returns the integral as it is. However, if I
 split up the integral into two portions, it quickly gives me an answer for the parts. Is
 there something implicit that I am missing in the Assumptions ?

Thanks,

MS.
