Proof step 60 from proof junkref-addobj-01 (previous step)

fis .keys = instfields(class), newref(r, st), class+∃(str, class), validfieldinits(fis, st), mkfs(class0, ty, fieldvar) ' ∈ instfields(class), is_referencevalue(addobj(r, class, fis, st)[r -- mkfs(class0, ty, fieldvar) ']), junkrefs(str, (addobj(r, class, fis, st)[r -- mkfs(class0, ty, fieldvar) ']) .refval ' + refs, ty, addobj(r, class, fis, st)), ∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st) ⊦ r = jvmref, is_abstract(class)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 59:
(addobj(r, class, fis, st)[r -- mkfs(class0, ty, fieldvar) ']) = refval(r0), fis .keys = instfields(class), newref(r, st), class+∃(str, class), validfieldinits(fis, st), mkfs(class0, ty, fieldvar) ' ∈ instfields(class), is_referencevalue(addobj(r, class, fis, st)[r -- mkfs(class0, ty, fieldvar) ']), junkrefs(str, r0 ' + refs, ty, addobj(r, class, fis, st)), ∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st) ⊦ r = jvmref, is_abstract(class)
