Proof step 14 from proof ac-init-first (conclusion)

⊦ class ∈ claset ∧ class ≠ `java.lang.Object' .class ∧ ¬ mkfs(class, void_type, `initstate' .field) ' ∈ fis → (init(claset, addclass(class, fis, st)) ↔ init(claset -- class, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 13:
class ∈ claset ⊦ claset = ∅, class = `java.lang.Object' .class, init(claset, addclass(class, fis, st)) ↔ init(claset -- class, st), # claset = 0, mkfs(class, void_type, `initstate' .field) ' ∈ fis
