Oscillating method of integration

Dear rooters,

I need to integrate over two dimensionl oscillating function (TMath::BesselJ(0,x*y), 0<x<inf, 0<y<inf). I use TF1 with IntegralMultiple, but the answer is not stable, a change in max_points leads to a different result. I tried to increas the number of max_points to 1e+6 but the result is still unstable. Is there some method of integrating over oscillating function with arbitry dimensions? (in my case it is dim = 2).

Thanks a lot!
