Minecraft crashes when joining any server

Put the summary of the bug you're having here
This problem has occured on Minecraft 1.10, 1.10.1, and snapshot 16w39c
What I expected to happen was...:
When I join a server, a lan hosted server or a public server(Cubecraft/Mineplex), it would load as normal and I would be able to play.

What actually happened was...:
The game crashes as soon as I load a world. The error report says it is due to not enough memory to run the VM, but I am running it with -Xmx2G, which has worked for me before. The only change I made to my system was that I updated my video drivers.

Steps to Reproduce:
Open minecraft. Join a server.
