Proof step 49 from proof cyclic-addobj (previous step)

fs = mkfs(class0, ty, fieldvar), fis .keys = instfields(class), validfieldinits(fis, st), is_obj(str, r, addobj(r, class, fis, st)), newref(r, st), ∀ fs, r0. fs ' × refval(r0) ∈ fis → ¬ junkref(str, r0, st) ∧ ¬ cyclic(str, r0, st), refs0 = [] ∨ fs ' ∈ instfields(class) ∧ is_referencevalue(addobj(r, class, fis, st)[r -- fs ']) ∧ refs0 .first = (addobj(r, class, fis, st)[r -- fs ']) .refval ∧ validrefs(str, refs0, ty, addobj(r, class, fis, st)) ⊦ r = jvmref, ¬ r ∈ refs0 ∧ ¬ dups(refs0), ∃ fs. fs ' ∈ fis ∧ fs ' ∈ instfields(class) ∧ fis[fs '] = refval(r)

Proof step 48:
fis .keys = instfields(class), validfieldinits(fis, st), is_obj(str, r, addobj(r, class, fis, st)), newref(r, st), ∀ fs, r0. fs ' × refval(r0) ∈ fis → ¬ junkref(str, r0, st) ∧ ¬ cyclic(str, r0, st), refs0 = [] ∨ mkfs(class0, ty, fieldvar) ' ∈ instfields(class) ∧ is_referencevalue(addobj(r, class, fis, st)[r -- mkfs(class0, ty, fieldvar) ']) ∧ refs0 .first = (addobj(r, class, fis, st)[r -- mkfs(class0, ty, fieldvar) ']) .refval ∧ validrefs(str, refs0, ty, addobj(r, class, fis, st)) ⊦ r = jvmref, ¬ r ∈ refs0 ∧ ¬ dups(refs0), ∃ fs. fs ' ∈ fis ∧ fs ' ∈ instfields(class) ∧ fis[fs '] = refval(r)
