Users are kicked from multiplayer server and are seen as a duplicate player when relogging

Users are kicked from multiplayer server when attempting to place or remove a block and are seen as a duplicate player when rejoining the server. Server is running version 1.8. I am unsure of how to reproduce the problem apart from logging into a server running 1.8 using an up-to-date client and attempting to place or remove a block.

The cause ist most probably a modded server, the result is MC-37586

Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report ([minecraft/crash-reports/crash-<DATE>-client.txt|http://hopper.minecraft.net/help/finding-minecraft-data-folder]) here.

Ok, not modded server according to crash report.

Can you provide the server.log ?

Added the latest server log that exhibited the problem.

Players are not kicked from the server, the client itself closes the connection:

I'm seeing the problem here:

[00:13:15] [Server thread/INFO]: <Illoradannan> Guardians don't die without water
[00:13:23] [Server thread/INFO]: <SirWombat> nope
[00:13:27] [Server thread/INFO]: <SirWombat> they just hop around lol
[00:13:42] [User Authenticator #3/INFO]: UUID of player Illoradannan is 4bd91e4f-331d-4245-b824-bb2e2772c6d8
[00:13:42] [Server thread/INFO]: Illoradannan/138.210.198.121:60856 logged in with entity id 34244 at (101.6851987578056, 45.0, 203.68631042800547)
[00:13:42] [Server thread/INFO]: Illoradannan joined the game

User Illoradannan is not recognized by the server as logged out, yet she is logged out from the client. Illoradannan then logs back in and sees a duplicate of herself on the server. I've attached a screenshot of the issue. (Edit: Removed duplicate image. Didn't realize I'd already posted said screenshot.)
