In the source code there is something called a SpinedBuffer that has better resizing characteristics than ArrayList but only supports addition of elements (no removal of).

SpinedBuffer holds an array of arrays (the spine), the size of individual arrays increases by some power of 2 as one goes down the spine.

A Spliterator, that has not been split, of SpinedBuffer returns N - 1 for the natural splits when N > 1, where N is the number of arrays in the spine.
