Proof step 13:
⊦ r -- sk ∈ st → r ∈ st
Proof step 16:
sk .fs = mkfs(class0, void_type, `initstate' .field), is_fskey(sk), jvmref -- sk ∈ st, jvmref ∈ st, ∀ class. (¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∨ st[jvmref -- mkfs(class, void_type, `initstate' .field) '] ≠ initval(error)) ∧ (¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∨ st[jvmref -- mkfs(class, void_type, `initstate' .field) '] ≠ initval(undone)) ⊦ _uninit ∈ st, st[jvmref -- sk] ≠ initval(undone) ∧ st[jvmref -- sk] ≠ initval(error)
