Hi Allen, could you provide an alternative proposal or a detailed explanation?  It is not clear to me although I have some clue from your previous comments.

Below is quoted from the "Decision Making" section in http://www.apache.org/foundation/how-it-works.html#meritocracy

  -1 -- a negative vote

The rules require that a negative vote includes an alternative proposal or a detailed explanation of the reasons for the negative vote.

> Same opcode are used for different operations between 0.20.security, 0.22 and 0.23. This results in failure to load editlogs on later release, especially during upgrades.
