Proof step 5 from proof ac-init-05 (previous step)

⊦ class1 = class2, (jvmref -- mkfs(class1, void_type, `initstate' .field) ') × initval(error) ∈ addclass(class2, fis, st) ↔ initerror(class1, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
class1 ≠ class2 ⊦ (jvmref -- mkfs(class1, ty, fieldvar) ') × val ∈ addclass(class2, fis, st) ↔ (jvmref -- mkfs(class1, ty, fieldvar) ') × val ∈ st
Proof step 4:
⊦ class1 = class2, jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st ∧ st[jvmref -- mkfs(class1, void_type, `initstate' .field) '] = initval(error) ↔ initerror(class1, st)

Rule argument
