Wow, thanks a lot for pointing this out!
Now, the Fourier transform is always applied to data of size windowSize:
double[] dft = new double[this.windowSize];
System.arraycopy(timeSeries.getData(), 0, dft, 0, this.windowSize);
this.fft.realForward(dft);
// if windowSize > mftData.length, the remaining data should be 0 now.
System.arraycopy(dft, 0, mftData, 0, Math.min(mftData.length, dft.length));
Any remaining coefficients should be 0 from thereon.
This should fix the issue.
