I get the following error message when I attempt to launch a server. 2014-12-30 17:22:17 [sEVERE] [ForgeModLoader] Unable to launch java.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(Unknown Source) at java.util.ArrayList$Itr.remove(Unknown Source) at net.minecraft.launchwrapper.Launch.launch(Launch.java:114) at net.minecraft.launchwrapper.Launch.main(Launch.java:27) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at cpw.mods.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:48) at cpw.mods.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:17)

So I get this error when launching a server can anyone explain it to me? It would be really help me. 2014-12-30 17:22:17 [sEVERE] [ForgeModLoader] Unable to launch java.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(Unknown Source) at java.util.ArrayList$Itr.remove(Unknown Source) at net.minecraft.launchwrapper.Launch.launch(Launch.java:114) at net.minecraft.launchwrapper.Launch.main(Launch.java:27) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at cpw.mods.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:48) at cpw.mods.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:17)

I am very disappointed in this server. We started out me and my 10 year old brother for a little time together. We really enjoyed the community, had a great time and were building a nice base. Then I come home today and he was kicked for the reason apparently "He was talking to much." I don't see any rules about chatting. And dude. He's barely 10. I mean seriously? I would highly suggest that you do not join this server because it looks like have been kicked for "Making there own server." So are we only allowed to do this server if we join? If you agree that my 10 year old brother should be reinstated please leave a comment. I can assure you, this is not, "A lucki server."

I'd like to join with my little brother: My ign: hyperwaffle Little bro's ign: bbbWaters

The waffle wants to join the server my exact ign is just like this forum profile but it is: hyperwaffle I hope to see you soon. I'm quite a tekkit veteran and I've decided to start showing off my builds on a server. My favorite mod is thermal expansion. Also my little brother would also like to join. We will probably be on at the same time and share a base. His ign is: bbbWaters thanks if you will consider adding me. Hope to see everyone soon! Also I would just like to say we are both mature and will be kind and friendly to everyone. Also just a quick question: I have one or two non-client side mods added to tekkit do I need to reset tekkit to join the server?

Ok so I tested with another friend and it worked for him. Only one friend having trouble and he was in my house on the other computer. Could that have something to do with it?

So I made a hidden modpack just for me and my friends and I sent a friend the platform address and everythings fine but right before it gets on it kicks them off. However it works just fine for me. Does this have something to do with the modpack being hidden? My friends could use my hidden custom modpacks before. Please tell me what I am doing wrong.

Thanks so much for this guide and doing this for us. Thanks to you I am now playing a custom server on a custom modpack I created.

Thank you. Couldn't have made my custom modpack without this being figured out!
