MC-80036Crash when generating world with certain custom preset
Minecraft hangs and even uses nearly no CPU after some time while creating or loading a customized world with the following preset code. My PC is definitely strong enough.

Invalid unless reproducible on a vanilla client.
Just reproduced with a vanilla client. I didn't think about it, because I nearly always play with Optifine. But yes, same error.
It doesn't crash on my PC. The loading screen doesn't disappear and in the task manager "javaw.exe" uses only a little percentage of my CPU.
Minecraft doesn't terminate, but look at the game output console of the launcher and in the crash-reports directory.
Confirmed for 1.9.4 and 16w21b, although I don't know how helpful it is, because I didn't test which part of the preset makes it crash. And because it takes about a minute even on a fast computer to be sure that it did crash and additional time to kill and restart the game, so it's tedious to test.
Confirmed for 1.10-pre1. It even goes to 0% CPU pretty quickly: As soon as the world generation started, I started the task manager, scrolled down to javaw.exe and it already had 0% CPU.
I have this issue in 18w20a with some normal old worlds. Crash log:
Maximilian Herczegh: Not quite.
This ticket: Exception in server tick loop
Yours: Exception generating new chunk
Your issue is
MC-125134I would then say that mine is a new issue (or another one I didn’t find). The main exception of my issue is that a random somehow got negative bounds. The main exception in the other issue is a custom RuntimeException which has something to do with chunks. Exception generating new chunk could probably be many different exceptions.
Maximilian Herczegh: Keep in mind that the symbols in the stack trace are obfuscated. The stack trace of some other snapshot in the description of
MC-125134is exactly the same as your 18w20a stack trace.
