Title:
FTB Custom Modpack failing during server start up
Launcher Version:
v1.4.7
Modpack:
FTB Infinity - Custom
Modpack Version:
v1.6.2 MC 1.7.10
Log Link:
Details of the issue:
After doing some research online, I read that if you want to setup tour own private server for just a few friends, you can just add and subtract mods from an existing modpack that you aren't using. I figured this would be incredibly problematic, but the client side with all the different mods works for the 3 of us, but I'm having some problems server side.

When I run the server it'll load for about 20 seconds before saying 'Press any key to continue', one of the last things it says is "[FML]: The state engine was in incorrect state...
After taking a look at the crash log I removed two mods temporarily, Journey Map and RF Tools, which seemed to progress the situation a bit further before crashing again with the same error.

I understand if this may be a difficult problem to analyse, and I have a feeling I may have missed out some important core mod(s).

This is my first post to the forum, and I know this is said a lot, but my apologies if this is posted in the wrong place. If there is a better way to do this, or if there is any other information you would like me to provide, such as the mods that I'm using, I can do that also.

Hi UniZero, thanks for your reply,

I updated my version of Java but I'm still having the same problems. Do you have any other ideas?

Caused by: java.lang.RuntimeException: Attempted to load class net/techbrew/journeymap/JourneyMap for invalid side SERVER

Remove journeymap from the server.

My last message which which included a pastebin of the of the crash log when removing Journeymap is still awaiting approval by a moderator, however I have made some progress.

After looking through the fml-server-latest.log in the logs folder of my server, I found that Damage Indicators was also causing some problems. After removing it I have now managed to generate a world, and from what I can tell the server is running fine. The two mods that have been removed that seemed to have been effecting the server were:

JourneyMap5.0.1_Unlimited_MC1.7.10
[1.7.10]DamageIndicatorsMod-3.2.3

Any idea why these mods might be a problem? They're not key mods, and I'll find a replacement minimap mod, but any ideas as to why they're not working would be appreciated.

However after the success of getting the server to work, my FTB Infinity pack is no longer working, client side, I believe this is an issue with a lack of compatibility between JRE8 and the FTB launcher, so a word of advice way be not to update to Java 8. :p

Java 8 should work without problems, lots of people do that. The reason why those 2 mods don't work server side is simply because they have nothing to do server side and thus were not written to be installed on a server.

They are client side mods, not server. When you load on the server the client side Minecraft logic doesn't exist. It's OK to remove them on the server - your clients should connect fine.
