Can confirm happens in 15w51b, was not able to reproduce with subsequent connections.
This message is repeated over a hundred times in the launcher console output when connecting to a server I own:

This also happens in singleplayer.

Yes, it's not really a difference.

Is this still an issue in the latest snapshot 16w44a? If so please update the affected versions.
This is an automated comment on any open or reopened issue with out-of-date affected versions.
Uriel Salischiker
Is this still a issue in the latest version of the game(currently 1.13.1)?
If so, please add it to the affected versions, thanks!
I got almost the same exception couple times a second (untill it crashes), while playing normal multi player.
