Proof step 3 from proof init-put-05 (conclusion)

class1 ≠ class2 ⊦ initerror(class1, st[jvmref -- mkfs(class2, ty, fieldvar) ', val]) ↔ initerror(class1, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
sk ≠ mkfs(class1, void_type, `initstate' .field) ' ⊦ initerror(class1, st[jvmref -- sk, val]) ↔ initerror(class1, st)
Proof step 2:
⊦ initerror(class1, st) ↔ (jvmref -- mkfs(class1, void_type, `initstate' .field) ') × initval(error) ∈ st

Rule argument
