    Description

      Directory creation causes excessive object allocation: ex. an immutable list builder, containing the string of components converted from the IIP's byte[]s, sublist views of the string list, iterable, followed by string to byte[] conversion. This can all be eliminated by accessing the component's byte[] in the IIP.
