SpongeForge crashes on startup on Minecraft Forge 1.11.2

Hi,

I have Forge1.11.2_13.20.0.2227 installed on Minecraft 1.11.2. By itself, or with other plugins, it works fine.

However, when I add spongeforge-1.11.2-2227-6.0.0-BETA-2237 to the mods directory, Minecraft fails to start, and the following log is created:
