Robert Muir commented on LUCENE-10149:
--------------------------------------
I ran tests again with {{gradle coverage}} and it looks all tested:
!Screen_Shot_2021-10-05_at_14.05.42.png!
But I looked at the unit test and it doesn't directly test these methods. Let's
improve this...
It does have a separate test for the whole Directory extending
BaseDirectoryTestCase so that's another avenue.

> ByteBuffersDataInput currently only optimizes the absolute {{readShort(long
> pos)}}, {{readInt(long pos)}}, {{readLong(long pos)}}.
> This is good because these are e.g. used by docvalues.
> On the other hand it should also optimize the relative {{readShort()}},
> {{readInt()}}, and {{readLong()}} in the same way. In some cases these are
> performance sensitive too. For example, the postings list compression uses
> {{readLong()}}.
> Looking at the code, this seems to be a simple oversight.
