Upon logging into the Hive server, (hivemc.eu) I received a crash report. I tried other servers and received the same result. I attempt to log on with a windows 10 computer (Minecraft Ver 1.10.1) and also received the same result.

The issue is caused by a modded server. Please do not create issues unless you are able to reproduce this on a 100% vanilla environment (Both client and server unmodded).
