Multiple Json errors randomly on startup

Are you using any add-on/resource packs?

@GoldenHelmet 
no, all vanilla sorry for late response. 

Is the error text showing every time you open Minecraft?

@goldenHelmet,only that one time

It's hard to say what happened, but we can only confirm a bug if we have some idea how to reproduce it. I am going to resolve this report for now. If you get more information or figure out how to reproduce the issue, please comment and it will reopen.

Had this happen to me on Windows 10, same error text displayed. It seemed to occur randomly on one load of the software. We used Minecraft many times before and after on that day without any error messages.

While looking at my game files for something else, I discovered a content log that matches the errors shown, which I have attached.

Hey, just checking in since this was reopened, is there any Updates to this bug that you can provide?

No updates, sorry. Usually the only update would be if Mojang states that it is fixed in a changelog.

This bug occurs very rarely, doesn’t have definitive steps to reproduce, and seems to have no impact other than looking bad. For those reasons I would expect it to be low priority.

Same thing for me. I usualy get these errors when starting up the game after a game crash.

Just adding my response in to keep ticket active, 

Looks like this has been affecting a lot of versions now. surely Mojang has to see this by now and a fix is incoming...
