Proof step 44 from proof validstatfields-put-other-statfield (previous step)

sk ∈ statfields(class0), initdone(class0, st[jvmref -- mkfs(class, ty, fieldvar) ', val]), tdname∃(str, class0), is_fskey(sk), ∀ class, sk. tdname∃(str, class) ∧ initdone(class, st) ∧ sk ∈ statfields(class) → validstatfield(str, sk, st) ⊦ class = `java.lang.Object' .class, tdname∃(str, class), validstatfield(str, sk, st[jvmref -- mkfs(class, ty, fieldvar) ', val])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 28:
⊦ is_fskey(sk) ↔ (∃ fs. sk = fs ')
Proof step 43:
sk ∈ statfields(class0), initdone(class0, st[jvmref -- mkfs(class, ty, fieldvar) ', val]), tdname∃(str, class0), ∃ fs. sk = fs ', ∀ class, sk. tdname∃(str, class) ∧ initdone(class, st) ∧ sk ∈ statfields(class) → validstatfield(str, sk, st) ⊦ class = `java.lang.Object' .class, tdname∃(str, class), validstatfield(str, sk, st[jvmref -- mkfs(class, ty, fieldvar) ', val])
