[1.16.5 Mixin Crash] Unexpected null pointer exception trying to find ModList.isLoaded when using older generation hardware

The only differences between all other players and this specific person's install is their CPU generation. They are using a 4th gen Core i7-4770, as noted in the log. However, all the other players I had have at least 9th gen or newer and no such crash has ever occurred for them. This seems to be a thread race condition that causes forgery to fail first, then takes down Redstone Control with it in a domino style, something to do with the server config mixin.

tl;dr seems to be an incompatibility with older hardware and Redstone Control, but only if older hardware is present

is there a way I can disable whatever feature would cause your config mixins to fail?

is it a JVM specific bug, should I continue instructing the user to try updating java?

is it a forge bug?

the patch couldof been released a month or so ago, and probably shouldof.
una does releases and i probably forgot to mention it at the time, and una operates on usa times so probably will be abit before a release.

commented

alrighty, I'll keep tabs on it :) will close the issue once I have a build to test with

commented

this seames like a duplicate of #580 , which was fixed in 3.1.5
which atm is unreleased; if you're in a hurry you can compile the 3.0/1.16 branch (you'll need forgeryTools, which uh you'd also need to compile)

commented

understood. sadly I have to wait for official curseforge release as it's only important for modpack use. Thanks!

as noted by #580 it must be because I have limited_runtime_configs enabled in my ini. I will disable it now to avoid the crash

commented

How soon are we expecting the patch? Attempting to disable the feature supposedly at fault didn't fix the issue for my user. I could try to compile but I'm busy today troubleshooting all the other projects I'm working on too.

is it possible that, unlike the mentioned issue, since I disabled the same config option and it didn't work, that it might be a separate issue?

commented

it's not a conflicting feature.
it's just a part of forge that throws when called too early.
limited_runtime_configs is generally better for compat, since it reduces injections, but it can't do anything in this case.

the issue is the same and was fixed a while ago just never released.

"it's just a part of forge that throws when called too early." - yeah I figured as much I was just making sure. it makes sense as well since forge's modloading order always does mixins before or alongside mod listing

what I mean to ask is there anything left on dev that needs to be done before the build can be uploaded to curse? I won't be able to release the pack update I'm working on until forgery is at least able to load into a world. As I mentioned before it works on my machine, but mine is miles faster than the problem machine

commented

downloaded the update, still waiting on the tester to give it a try

commented

late follow-up but the patch did fix my issue, thanks again.
