Same error for me

The workaround also works for me.

I have the same problem, and I also have the same processor, operating system, and the newest version of Java (Version 8 update 161).

I get this error in the launcher:

Unreported exception thrown!

Edit: This only affects when I try to log in to a multiplayer server. I was able to open the game on my local machine, and after that I uploaded the world I generated so it was the same exact thing both places. I can open it locally but not from the server. I use NFO Servers, it's a managed Minecraft VPS.

This affected me in both 18w07b and 18w07c.

EDIT: I do have a crash report.

I am having the same problem with my multiplayer server. The game would crash when I logged in, so I deleted my player file, just in case it was some corruption in the chunks I was in, and it worked – until I decided to start putting lots of cute, colorful parrots around the spawn area. After spawning about 15 or 20 parrots, the game crashed again. The area I had been in prior to deleting my player file also had parrots (also spawned from eggs).
