Robert Muir commented on LUCENE-8165:
-------------------------------------
attached starter patch that fixes BytesRef/CharsRef/IntsRef/LongsRef to just
use good old arraycopy and adds tests. There are a lot more usages to fix but
it demonstrates the problem.
> ban Arrays.copyOfRange with forbidden APIs

> This method is no good, because instead of throwing AIOOBE for bad bounds, it
> will silently fill with zeros (essentially silent corruption). Unfortunately
> it is used in quite a few places so replacing it with e.g. arrayCopy may
> uncover some interesting surprises.
> See LUCENE-8164 for motivation.
