I'm getting an Initialization error that I don't understand and doesn't say what kind of error it is in my Init()

 

It happens on my armor registering, which uses custom code, not vanilla's.

 

This is the error:

Can anyone help?

Ytt, Because the armour system adds more properties and mechanics I believe. (I did not originally write this code,I'm joined the author in updating from 1.7.10 to 1.8)

Ok, I see the error is line 38. I read somewhere that this should be added in preinit() before armors are registered. But here, the only use for it is just a dummy material that needed to be passed through to keep the system working. So I'm not sure how to change it.

The actual error is not EnumHelper. The problem is that you are using the field "design" (declared on line 34 in your paste) before you actually assign any value to it. You use it in line 38 but the value does not get assigned until the constructor. Why do you set static fields in the constructor? That is a bad idea pretty much 99% of the time.
