Server Crash After Java Update

Hey Guys! So I Had A Bunch Of Mods Loaded Up On A Server Hosted From A Pc With MineOS On It And SpongeForge Didn’t Load Up (I Knew This Because In The Forge Log I Didn’t See Anything About SpongePowered Loading Up And “/Sponge” Was Not Found As A Command In The Console/Game). I Then Updated Java On The Pc To Java 1.8.0 u66 ( Think, Or Whatever The Latest Version Is/Was On The Date Of This Thread’s Creation) After That, I Kept On Getting Crash Reports WITH Something About SpongeForge In It But I Kinda Need Help Deciphering What The Problem Is. Here Is The Crash Report:

Remove desert wells and try again

A mod should not be removing classes from he base game, however, if you can, please provide the full server log.

Okay. Sorry For The Long Wait (Due To School & Swimming).
Here Is The Crash Report Without Desert Wells:

Here Is The “latest.log”:

And Here is The fml-server-latest.log":

Just an educated guess here, but the FML log file ends with featherchat. That plugin may be your problem, as I think it is outdated.

Well there’s a bunch of errors in that log file

[00:26:55] [main/ERROR] [FML/]: Unable to read the jar file Core.jar - ignoring error in opening zip file
[00:26:55] [main/ERROR] [FML/]: Unable to read the jar file CoreChat.jar - ignoring error in opening zip file

[00:26:55] [main/ERROR] [FML/]: Unable to read the jar file CoreZones.jar - ignoring error in opening zip file

These files are corrupt. Re-download them.

The log fml-server-latest.log got chopped off, it reached pastebin’s limit so I can’t see the actual crash happen.

The crash is most likely an outdated plugin. Make sure you update all plugins and use the latest spongeforge.

(Note to @gabizou it’s not that the class was removed, see the cause:

Exception in class transformer from coremod DesertGenLoadingPlugin
Caused by: java.lang.NoClassDefFoundError: grim3212/mc/core/util/GrimLog

Their transformer broke on something

Note to @Inscrutable The log file was chopped, that’s not the end, in fact, it’s just the beginning Sending event FMLConstructionEvent to mod featherchat


Thanks! I Removed The Core Plugins And Used EssentialsCMD Instead! Everything Is Working Now.
