IMO, this PR or DRILL-6202 is not the best place to discuss boundary
checking as the PR and JIRA deals with `IndexOutOfBoundsException` but does not
change how DrillBuf, Vector or Operators ensure that reads and writes are done
within proper boundaries. I'll bring that to dev@drill. Please repeat your
arguments on the mailing list. ---
