1.12.2 - Server - ConcurrentModificationException
LotuxPunk opened this issue ยท 6 comments
Forge version: 2836 (1.12.2)
Twilight Forest version: twilightforest-1.12.2-3.8.689-universal.jar
Link to crash log: https://pastebin.com/VH9VUFsG
Steps to reproduce:
- Generating terrain (Twilight) on my server
What I expected to happen:
- No server crash
What happened instead:
- Server crash
The stacktrace seems to mention the Tardis mod. Has this been reported to them, too?
Also, just in case there is a change in later versions that may fix this, can you try Twilight Forest version 3.9.888?
world.func_175690_a 1.12 is setTileEntity, which is what causes the concurrency issue. I'm pretty sure the issue has to do with the Tardis mod, as the initial call to it is from func_72939_s which is world.updateEntities.
So, it's already iterating over the entity list to update them, meanwhile one of those tile entities causes chunk loading which tries to create & then add a new entity to the list that is currently being iterated on. Hence, concurrency.
Ruins is the one that's actually doing the chunk loading, though (onEntityEnteringChunk is calling wold.getChunk), so it's potentially not entirely Tardis mod's fault.
I'd investigate to see if it still happens with just Ruins installed, or just Tardis installed, or neither of them installed.
This does not appear to be an issue with TF, but I will look into it regardless as it may also not be a simple mod issue.
Hey !
Apparently, even with the beta build 3.9.888, CME still happen.
Do you want I transfer this issue to Tardis Mod ?
