We have got two server crashes that seem to be related to FoodContainer. We are using the latest versions so far. All versions and configs can be found here: https://github.com/BakermanLP/ModpackProjectRETv7

Server runs on cauldron and forge 1207.

First one, a player tried here to add "Beef Wellington" to the food container:

I honestly have no idea how this is possible or what I can do about it. From the Java documentation about the error:

Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.

I guess try redownloading The Spice of Life to make sure your jar isn't corrupted somehow.

Ohhhh... wait, I know what's happening. I'll fix it soon.
