Robert Muir commented on LUCENE-8164:
-------------------------------------

Basically was looking at this in response to Tony Ma's thread on the user list 
"Lucene 4.5.1 payload corruption - ArrayIndexOutOfBoundsException"

I'm not sure what IW actually does with it, but e.g. if it actually writes less 
bytes than {{offset + length}}, then i can see pointers getting screwed up or 
something. Maybe the test would need to write enough to produce skipdata or 
whatever to get an obviously corrupt index.

> IndexWriter seems to be missing bounds checks for payloads completely.
> If you pass a "broken" payload (e.g. BytesRef's offset + length is out of 
> bounds), it will silently index it as if nothing went wrong. What actually 
> happens? Doesn't matter, we should be getting an exception.
