Proof step 25 from proof validstatfield-addclass-other (previous step)

⊦ class0 = class, class = `java.lang.Object' .class, validstatfield(str, mkfs(class0, ty, fieldvar) ', addclass(class, fis, st)) ↔ validstatfield(str, mkfs(class0, ty, fieldvar) ', st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ validstatfield(str, sk, st) ↔ is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ (initdone(sk .fs .class, st) → validfield(str, jvmref, sk, st))
Proof step 24:
⊦ class0 = class, class = `java.lang.Object' .class, is_fskey(mkfs(class0, ty, fieldvar) ') ∧ mkfs(class0, ty, fieldvar) ' ∈ statfields(mkfs(class0, ty, fieldvar) ' .fs .class) ∧ tdname∃(str, mkfs(class0, ty, fieldvar) ' .fs .class) ∧ ( initdone(mkfs(class0, ty, fieldvar) ' .fs .class, addclass(class, fis, st)) → validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', addclass(class, fis, st))) ↔ validstatfield(str, mkfs(class0, ty, fieldvar) ', st)
