Proof step 6 from proof nouninit-put-01 (previous step)

∀ class. class ∈ claset → ¬ initundone(class, st), class0 ∈ claset, initundone(class0, st[jvmref -- mkfs(class, void_type, `initstate' .field) ', initval(error)]) ⊦ claset = ∅, # claset = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ rk ≠ _uninit ∧ rk ≠ jvmref -- mkfs(class, void_type, `initstate' .field) ' → (initundone(class, st[rk, val]) ↔ initundone(class, st))
Proof step 5:
jvmref -- mkfs(class, void_type, `initstate' .field) ' ≠ _uninit ∧ jvmref -- mkfs(class, void_type, `initstate' .field) ' ≠ jvmref -- mkfs(class0, void_type, `initstate' .field) ', ∀ class. class ∈ claset → ¬ initundone(class, st), class0 ∈ claset, initundone(class0, st) ⊦ claset = ∅, # claset = 0
