Subject Re: java.lang.NullPointerException on some commands (stats, conf)
Date Wed, 01 Jan 2020 19:12:44 GMT
I am not sure, based on the email... Mike, can you clarify?

I tested it on the master branch and ruok sent back the same small JSON for
me on both secure-only and unsecure deployment. Although I haven't tested
it on 3.5.

Kind regards,
Mate
