Proof step 2 from proof init-put-02 (conclusion)

⊦ r ≠ jvmref → (initerror(class1, st[r -- sk, val]) ↔ initerror(class1, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

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

Rule argument
