Repairing Normal Noise Function

I am currently working on getting some generator files working, and I'd like to add noise to the data. I am attaching the generator file ackley-10D.generator as well as the relevant java file NormalNoiseFunction.java. There were some errors that I had to work through regarding parsing the configuration properly, however I think that part is alright now. Where I'm still questioning/stuck is in lines 77/78 of the 'apply' function. In the original, the list of distributions is accessed at index i (0 <= i < # dimensions). However, I only provided 1 distribution to the generator file. My question is whether it is expected that I provide 10 distributions (i.e. however many distributions I have dimensions) in the generator file. Or whether this is a bug. Or whether I've understood something wrong entirely.
