Is that now about an odd chance that the array/ArrayList might 
grow beyond the initial estimate?  Or is that about other code
(that sees the ArrayList) that may be relying on that the last
non-null element is at position "size()-1" ?

If the former: for an odd-chance event, doing
  addAll(...nCopies(...))
is good enough.

If the latter: stick to Vector ;-/  Even if ArrayList.setSize()
was ever added, that would surely happen too late for your project.
