ArrayList iterator back() bug fix, compute remaining correctly #314

Closed barakugav closed 5 months ago

barakugav commented 5 months ago

The current implementation of ArrayList.iterator().back(int n) compute the number of remaining elements wrongly. It compute size-pos, which is correct for the skip(int n) method, but wrong for the back(int n) method.

Together with https://github.com/vigna/fastutil/pull/291, these bugs are kind of limiting the use of the lists. Is there a plan for a new release soon? @vigna
