I am a little puzzled by this exception, because the implementation here is the same as the one used by forge to load crafting recipes.

Are you actually able to use minecraft with just forge installed on top of it?

I had the same issue with EnderIO. Look into their repo. They added code complete as label to this issue.

The one that you have entered there actually was a very different crash. Could you test if you can run just forge without any additional mods?

I will test that the next days.

I have investigated a bit more and it seems to relate to a corrupted java installation. There are reports of the same issue for forge where reinstalling java fixed it.

So I am going to close and suggest people try to reinstall java if they get this. Let me know if you're able to recreate even after reinstall.

OS: Ubuntu 17.10 GNOME 3.26.2 (amd64)
Java: 1.8.0_171
Minecraft 1.12.2
Forge: 14.23.4.2756

I am getting the same crash as NickelHub. Minecraft runs fine with forge alone installed, but crashes as soon as I try to add Reliquary. Forge also runs fine with additional mods installed as well.
