Yes, version 2.6.5 only works with Bukkit till version 1.7.2. For anything newer you have to use the 3.0 beta. It is extremely stable and just labeled beta because I still have no make some internal changes to add support for Sponge (and hardly find the time to do so).

Generally the beta versions on BukkitDev are fine, but for 1.12 you have to use a devBuild.

Dev build works great.
Thanks

P.S. Might be good to "h1." and red the note on that page about 1.12!

I cannot reproduce this using the latest CraftBukkit version. Are you sure that you are using the latest version of CraftBukki/Spigot? Could you post the output of the /version command?

commented 
$ ./send_command.sh version
>version
This server is running CraftBukkit version git-Bukkit-015bda4 (MC: 1.12.2) (Implementing API version 1.12.2-R0.1-SNAPSHOT)
Checking version, please wait...

Strange, what does /version mywarp print?

commented 
$ ./send_command.sh "version mywarp"
>version mywarp

I got it from the Bukkit site, maybe it's the wrong jar?
