Proof step 9 from proof initerror-05 (previous step)

st[jvmref -- mkfs(class1, void_type, `initstate' .field) '] = initval(error), init(st), jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st, jvmref ∈ st ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ init(st) ↔ (∀ class1. initdone(class1, st))
Proof step 8:
st[jvmref -- mkfs(class1, void_type, `initstate' .field) '] = initval(error), ∀ class1. initdone(class1, st), jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st, jvmref ∈ st ⊦

Rule argument

[crewrite-arg: init-04, F, [st] → [st]]
