Running FTB Infinity 2.0.2 with a few extra mods installed.

We are getting a server crash and reboot after a user logs in.

http://pastebin.com/s8bJ0JkV

Looks like an issue with his farming station when he loads his chunks. I talked with the user he has 2 farming stations, one is not powered currently, the second has power, me import bus and is farming Ender Lilies, nether wart, cotton, and a few magical crops. It currently has an amethyst hoe in it. We have several other users with Farming stations setup and working with no issue, it is just this one user.

Let me know if you need any additional information.

Thanks.

(I'm the user) We also tried rolling to the latest version (from a few days ago), as well as updated both EnderIO and EnderCore. It seems like when I login the chunk loads, and something odd happens. I wasn't touching the active, or inactive, station, or even in the same vicinity. The active one has been running with these plants for a few days. The only changes to it have been to add more magical crops, and remove some of the cotton, but of the same type of magical crops, no new plants.

We did have it doing essence berries, but that caused random berries, so we disabled it using the property (as it seems it's happened to others before).

related/duplicate to #2957

Yes, that's the same crash.

It seems that either the fake player or the world object that is part of it are not there. Really funny business; it's not as if we had a change there recently. I'll see to put some sanity checks into the next version.

PS: Thanks for this stacktrace, that actually helped. With only the first one there were too many possibilities what it could be.

Could you please check your logfile for the server startup: Does any mod claim to patch net.minecraft.server.management.ItemInWorldManager.func_73078_a() or net.minecraft.server.management.ItemInWorldManager.activateBlockOrUseItem()?

Linked to duplicate #2985, closed parent.

I am not seeing any in the ones that i looked at before taking off for work. I will do a search on all the server logs later today and let you know/attach the log files if i find any. Thanks for jumping on this and helping out.

Sorry for the slow response, I have looked through the log files and do not
see any of the lines you asked about.

No problem, I didn't really expect you to. I just wanted to make sure...

The latest version contains a change that might help. I'd really like to get some feedback on this. Thx.

I was running 2.2.8.381 on my server and we had no issues using farming
stations. After the upgrade to 2.3.0.417 is when it broke. At this point
I have rolled my server back to a date before the issue came up and just
destroyed all of the farming stations. This seems to have fixed the crash,
but I have told everyone to not use the farming stations or killer joe
until we get a fix. I did make a clone of the container before i did the
roll back so i could test new code when it is released to see if it will
fix the issue.

Let me know if you would like any more info. Like I said i have a clone of
the server that will crash and can test/run anything you have to verify it
fixes the issue.

Just read that again, I will download the new version and try it on my
clone to see if it takes care of the problem.

Thanks

I put the new version of EnderIO and EnderCore on the clone and started the server. After login with my client I went to the players base and the server crashed as soon as the chunks loaded.

Here is the crash report with the new versions installed.

http://pastebin.com/WPqTERZi

Let me know if you need anything else or would like me to test something different.

I'd like to send you a debugging version, because you have such a nice test setup. Would that be possible? You'd need to temporarily install immibis microblocks for it to run, as I cannot compile a version of ender io that runs without it (bug in Oracle's compiler).

Sure, just let me know what i need and how you want it setup.

Great.

You only need to add Immibis Microblocks and Core from http://immibis.com/mcmoddl/ --- you can trow them out afterwards.

Then use this version: http://loenwind.info/eioa/EnderIO-1.7.10-2.3.0.419a_beta.jar

Let it crash and look at the logfile. If it crashed at the same position (in PickableFarmer.harvestBlock) there will be a big debug output directly above the crash. That's what I want to see.

If it crashes somewhere else, try again. If you cannot get it to crash in PickableFarmer.harvestBlock again, I have to make a version with more debug points.

np, I have everything downloaded and will get it on the server and tested after work tomorrow. I will let you know what happens/provide you with the data.

thx very much

Ok i have tested the mod and am getting a different crash. I have attached
the crash report and the log for you to review. Let me know when you are
ready for me to retest or want me to change anything.

Ok i have copied and verified the immibis core file is in the mods folder
and i get about the same error as yesterday. I will link the crash report
just to make sure i am not missing something. I will also look into
immibis as i have not used it before and maybe i am missing something in
the setup/conflict with another mod i have installed.

Please ignore the post above, i was missing the core, only had the
multiblock, I have it now and the server boots but as soon as the world
loads it does a reboot with a different error then the farming station.
Let me play around with it for a few and see if I can get something
different. If not I will post the crash report and see if that has
anything helpful.

Ok, one thing I can say for sure: Some mod is changing Minecraft's player class heavily. There's a field missing that should be there, and my debugging code is crashing when trying to print its value.

Here's a version that should not crash if there's something missing from the class: http://loenwind.info/eioa/EnderIO-1.7.10-2.3.0.419b_beta.jar Maybe that will give us some data on what's actually happening...

there are not that much mods in his list that change the player class to add additional slots and stuff
baubles f.E. .. i dunno but i may remember Xenos Reliquary adds stuff to the player too

sweet i will get this one loaded up tonight and send you all the data.

the fml server log you posted is from the restart of the server (starting at 15:56:19) after the crash (at 15:56:14). I'd need the one with the output just before the crash...

thx again for doing all this testing!

my bad they had the same time stamp so i grabbed the wrong one. Here is the
correct file:

Ok all looks good, With that version I was able to login with no issue. I
went to the farm station with a watering can to force a bunch of plants to
grow and get harvested. All looks good. Thanks again for all the work in
getting it fixed. I will be waiting with anticipation for the next
release. Also just throwing it out but if you guys need a test bed again
just let me know. My current setup uses containers so i can clone my
active world/server and run them side by side with little effort.
