Proof step 7 from proof addobj-initerror (previous step)

⊦ r = jvmref, initerror(class0, addobj(r, class, sks, st)) ↔ initerror(class0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ initerror(class1, st) ↔ (jvmref -- mkfs(class1, void_type, `initstate' .field) ') × initval(error) ∈ st
Proof step 6:
⊦ r = jvmref, (jvmref -- mkfs(class0, void_type, `initstate' .field) ') × initval(error) ∈ addobj(r, class, sks, st) ↔ initerror(class0, st)

Rule argument
