Github user vrozov commented on the issue: https://github.com/apache/drill/pull/1144 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.
