I think you need to relearn quantum mechanics. Your understanding of quantization is lacking. The boundary conditions gives a discrete set of oscillation modes true, but that's not what quantization is. Quantization is the fact that each mode will be occupied by an integer number of particles. In classical physics each mode may have any amount of energy.
This is probably just a misunderstanding. Apparently, parkner meant boundary conditions for the ##\psi## function of harmonic oscillator. These indeed play role in obtaining preferred values of energy ##(n+\frac{1}{2})h\nu##.

Informally... If light can only be emitted in quantized packets, then if there's not enough energy concentrated in one area of the object to create a packet of light at a given frequency then nothing at that frequency will be emitted. The higher the frequency of the light the more energy is needed, and the hotter the object the more energy is likely to be concentrated in one area. Combine these two results and you conclude (after some fairly huge oversimplifying of stuff discussed in that other thread) that for any temperature there are frequencies high enough that they're unlikely to be emitted; and that the hotter the object the higher the frequencies that will be emitted can be.

Is that related to Boltzmann distribution ?
