Server will not start when adding Sponge

[simon816]

One thing you could try is to launch the server using the SpongeBootstrap I made, see here:

SpongeBootstrap - Fixes ordering issue with other coremods

This is a bootstrapper to launch SpongeForge with maximum priority. There are some issues with other coremods where they load classes before SpongeForge’s mixin system is able to transform them. To run, simply call java -jar SpongeBootstrap-{version}.jar IN PLACE OF a forge jar. All arguments are transferred to the actual forge launch. Download Link, Source Code Note The bootstrap simply checks if required files match the following filename patterns, hence you must have the original filenam…

(you will need to rename the FTBserver .jar to have the phrase “forge” i.e. forge-1.10.2-12.18.2.2124-universal.jar for the bootstrap to pick up the server)
