SpongePowered error Crash

So I never heard of SpongePowered before or used it before. The main error im assuming is: Caused by: java.lang.SecurityException: class “org.spongepowered.asm.service.ServiceInitialisationException”'s signer information does not match signer information of other classes in the same package.

Google was no help nor was any other forum posts on here. So if anyone can help me that would be great. Posted before is a Paste.gg with the (most likely) complete mod list and the most recent crash log.



So the issue your facing isnt fault of sponge, but instead a mod that has sponge “Mixins” which is a tool designed to make hooking into Minecraft a lot easier.

The bad news is its not obvious on what mod(s) use mixins and also what mod(s) cause the crash your having.

The good news is you can find out which mod(s) have mixins easily which will narrow down the culprit.

Sadly Sponge is not responsible on how Mixins are used in other mods so our help would stop at narrowing down which mods have mixins.

To find out which mods have mixins:

  1. You will need the mods folder on your local pc
  2. install a Zip viewer (such as WinZip, 7Zip, WinRar, etc)
  3. right click a mod in the folder
  4. open it in the ZipViewer (in windows its “Open With” ->)
  5. open the folder labeled “org” (it will be on the first page, if it isnt then this mod doesnt use mixins)
  6. open the folder labeled “spongepowered” (if it isnt there then this mod doesnt use mixins)
  7. take note that this mod uses mixins
  8. go back to step 3
