The patch is updated to:

* use Peter’s approach to avoid allocating an ArrayList when length <= DEFAULT_BUFFER_SIZE;
* use the default ArrayList constructor instead of that with a specific initial capacity;
* update the test to ensure that lengths which require three buffers are covered.

Thanks,

Brian
