(markus6890) Error then loading citizens

[agile cargo]

I created an issue on the Citizens GitHub and was asked to go her
https://github.com/CitizensDev/Citizens2/issues/3268

anyway when my paper 1.21.8 server tries to load Citizens it comes with an error and will not load the plugin
I have tried to remove the plugin and delete the citizens folder and then reinstalled it but it had no effect
Can someone help with my problem?
The error: https://paste.denizenscript.com/View/135604
server version: This server is running Paper version 1.21.8-35-main@b200237 (2025-08-15T21:04:16Z) (Implementing API version 1.21.8-R0.1-SNAPSHOT)

Info: logs

Please post your full latest log file.

Background Info: One of the most helpful tools to identifying the source of a problem is your server logs file! Logs contain all sorts of important information like server and plugin versions, any error messages, and a lot more important information (More Info).

How To: Your log can be found in the logs folder within your server folder. The most recent log is a text file labeled latest.log. To get help using these logs, please open that file in a text editor and copy all of the text, then open https://paste.denizenscript.com/New/Log and paste the text into the box on the page. Then click "Submit" and copy the URL and paste that back into this channel.

Please do not upload the file to Discord or to other pastebin services, use the log pastebin linked above.

Potentially Bad Line(s)

Starting Minecraft server on 0.0.0.0:50003 - server is offline but has no address bind. This might mean you're using a system level firewall, but if not, it means your proxy is bypassable by hackers. Either enable a system level firewall, or bind your server to localhost in server.properties via server-ip=127.0.0.1.

[crystal pier]

Hmm give me one second

[crystal pier]

I'm not able to recreate this issue using the same basic setup, are you still encountering this when Citizens is the only plugin on the server?

[agile cargo]

can you send me the version you use so im sure my version is'nt somehow bad

yes im still getting the error with only Citizens-2.0.39-b3891.jar on my server

[crystal pier]

i'l using the same version of citizens you are, only difference is i'm using paper 1.21.8-36 instead of 35, but the change between those doesn't have any effect on what it looks like this issue is

[agile cargo]

i have disabled PluginRemapping does that cause problems with Citizens
-Dpaper.disablePluginRemapping=true

[tacit cape]

yes, why did you disable it?

[agile cargo]

Because if it was enabled it would not remap all the plugins including citizens but I might be the server that is sick somehow.

[tacit cape]

you should remap the plugins

[agile cargo]

Okay I will try it later

@agile cargo

[agile cargo]

Okay i have enabled Remapping even fully reinstalled my server it remaps the plugin when i start it the first time but when i restart the server it throws this https://paste.denizenscript.com/View/135630

[tacit cape]

need to remove plugins/.paper-remapped

@agile cargo

[agile cargo]

i have done that after a restart the folder comes back and citizens works but after restart it comes with the error again

[tacit cape]

this is a very weird error that only you have reported, I would say that you need to wipe a few things in your server

I would reset everything except your plugin folder and world folder

[agile cargo]

i have completely reinstalled the server today it is as fresh as it can be.
Okay i got i to stop throwing that remapping error i saw that inside .paper-remapped there where a citizens.jar i overwrote it with the one i have in the plugins folder. but now it throws this error
https://paste.denizenscript.com/View/135631

[tacit cape]

@agile cargo again, these are weird errors that nobody but you is reporting

[agile cargo]

iknow and i don't understand why im getting it.
I your test server does Paper remap your citizens.jar file?

[tacit cape]

yes.

[agile cargo]

it might be a RAM issue how much RAM does your startup command allocate fx -Xms128M

[tacit cape]

there's no minimum ram allocation in my test server

[agile cargo]

okay somehow it works now when i slowly put one plugin on at a time so i might be it has to little RAM allocated on start

yep it was RAM if you don't have allocated enough RAM in the startup command it can throw the errors i got

Thread closed as resolved.

that probably isn't really resolved then imo

Thread Reopened

Thread was manually reopened by @idle bolt.

[tacit cape]

??

[idle bolt]

it's failing with ?not enough maximum ram allocated? but the error is about a missing class? It seems too much like a race condition

[tacit cape]

it was an issue with disabling paper plugin remapping that is now resolved

please don't reopen threads on behalf of other people

[idle bolt]

can u point me to the commit that resolves it?

[tacit cape]

there's no commit

it was user error

[idle bolt]

this was the solution the user mentioned..

btw, not that i think this sentiment of not being able to open an issue that you don't think was actually addressed is valid.. but i actually recognise the issue from when i had previously tried on 1.21.9 (https://github.com/CitizensDev/Citizens2/issues/3271) namely here: https://paste.denizenscript.com/View/136363

and i never disabled remapping..

[tacit cape]

this is not the same issue

if you want to make a new issue then make a new issue

but it's actually not a productive use of my time being in this thread

[idle bolt]

my concern is my own plugin relies on yours.... if you 'solve' issues like this then im fucked??

like you know, im screwing over my own community by having it as a dependency

im kinda relying on you for my own stuff to work nicely

which idk if u get it, but it's a little frustrating

[tacit cape]

this issue was solved.

[idle bolt]

i will spin up paper 1.21.9 with 2.0.40 rn, and i will get this issue and will show u the log. No remapping disabled.

[tacit cape]

re-read the version in this thread.

[idle bolt]

would be kinda crazy for a regression that prefectly aligns with the issue details to happen.. aside from the fact there was no changes made to do with this issue anyway but since ur time is the only time that apparently matters here is the same version

https://paste.denizenscript.com/View/136435

https://paste.denizenscript.com/View/136436

^ without any other plugins too

[tacit cape]

the author of this thread was on 1.21.8

so there is no point testing on 1.21.9.

[idle bolt]

u gen believe there is no relation?

[tacit cape]

I've been a plugin developer for 13 years, I know there is no relation

[idle bolt]

alright then..
i don't think im gonna make an issue for this occuring in my case tbf. Sorry for wasting your time.

[tacit cape]

perhaps you can look up why NoClassDefFoundErrors might happen

so you can learn why this issue is not the same
