Classical optics is solved using Maxwell's equations, which are both equivalent to the wave equation for light. A treatment of Maxwell's equations around a screen with 2 slits shows that light entering the screen self-interferes, which is only possible with particles.
Thus the only remaining answer is that the black-body radiation problem was evidence for the particle nature of light. In this problem, assuming the energy levels of light were quantized meant that the predicted energy contained in EM modes in a box was finite.
