I think it may also be related to how I have global groups set up as the world the users are teleporting to/from uses different groups.

I'll take a look at this issue later today / this week if I have time, however I'm a bit busy with university at the moment. By the looks of it, as this issue is crashing the server once fixed it should resolve https://dev.bukkit.org/bukkit-plugins/bpermissions/tickets/743-bperms-opping-issue/ as this issue indirectly causes that issue.

Also, it might help if I have a couple of your world permissions files to help when reproducing the issue.

First off I'd like to once again thank you for taking the time to maintain this plugin so well.

For a seemingly quick fix to this issue I disabled using global users and simply mirrored one world on them all. Obviously this is not ideal as it means I can't have changes between the groups in the worlds.

This change however has seemed to fix the issue so it is likely related to the "use-global-users" option. I'd also like to make a note that errors were both thrown when users were swapping worlds and when virtual players were swapping worlds but not seemingly every time.

As for the indirect cause to the other issue it would likely be a fix but I would like to say that this issue happened months ago too with a different crash type (you might recall my permissions nightmare back then). I just never reported it as I didn't confirm it was bperms.

OK, I think I have a solution in the form of http://rymatemc.co.uk/jenkins/job/bPermissions/172/

Test it and see if it works for you!

@rymate1234: Go

Sorry for the very late response. Going to run this build from now on, thanks for the potential fix!

Seems to get this error? http://pastebin.com/ZpjcSfTX

@LaughNgamez: Go

Did you download bPermissions-Bukkit-2.12-all.jar?

@rymate1234: Go

Yeah, should I not have?

@LaughNgamez: Go

That's the right jar, but the error seems to imply you downloaded the 90kb bPermissions-Bukkit-2.12.jar, which is an incomplete build that gets published on jenkins for some reason.

@rymate1234: Go

Huh will look into (maybe I did by accident?)

Edit: Upon checking I certainly did

@LaughNgamez: Go

I've just downloaded the same build you downloaded and it seems to start fine on my test server. Not entirely sure what the issue might be then ._.

Maybe a corrupt download? Accidently got two bPerms jars in the plugins folder? A ghost invaded your server? I've checked everything I can think off and the file "de/bananaco/bpermissions/util/loadmanager/MainThread" deffo exists.
