8 years ago I seem to be able to reproduce it by laying out a recipe involving forge microblocks on the easy crafting table, and leaving it jammed trying to find blocks to cut. The easy crafting table (with my changes) will check, when a hopper tries to insert an item, if that item is a valid substitute for the missing crafting ingredient in the given recipe. Ultimately, it seems like MicroMaterialRegistry$.getMaterial crashes when triggered immediately upon server startup, in this case, due to hoppers trying to insert items into an auto crafting table.

I am getting this crash on startup, from a test world where I was testing changes to Easy Crafting:
