Proof step 6 from proof validstatfield-addobj (previous step)

sk .fs = mkfs(class0, ty, fieldvar), is_fskey(sk), newref(r, st), tdname∃(str, class0), sk ∈ statfields(class0), initdone(class0, st), validfield(str, jvmref, sk, st) ⊦ r = jvmref, validfield(str, jvmref, sk, addobj(r, class, fis, st))

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 5:
sk = fs ', fs = mkfs(class0, ty, fieldvar), is_fskey(sk), newref(r, st), tdname∃(str, class0), sk ∈ statfields(class0), initdone(class0, st), validfield(str, jvmref, sk, st) ⊦ r = jvmref, validfield(str, jvmref, sk, addobj(r, class, fis, st))
