I spot-checked it and it seems OK, but I'll let Nir and Ambarish review it in more detail. One question I had was around the changes to remove one of the overloads of `mergeSort` (the one without a `Comparator` arg) from `SortHelper.java`: I presume you have verified that you won't ever get an NPE due to a null `Comparator`?
