Making a superflat world with one layer causes an Exception, because there is hardly any heap space:

no need, the bot is programmed to see if your crash report contains certain lines, if it does, it'll auto-resolve to the correct ticket

@[Mod]FVbico: I created another issue, MC-99899 involving the spam i said about in my latest comment. Going back to this issue, you can close this issue, I think the full report is in MC-12949.
