And obtained the following new goals

Proof step 6:
(addobj(r, class, fis, st)[r -- sks0]) = refval(r0), fis .keys = instfields(class), (addobj(r, class, fis, st)[(addobj(r, class, fis, st)[r -- sk]) .refval -- sks1]) = refval(r0), is_referencevalue(addobj(r, class, fis, st)[r -- (sk ' + sks1)]), disjoint(str, fis .vals .nonnullrefs, st), fits(r, sk ' + sks1, addobj(r, class, fis, st)), fits(r, sks0, addobj(r, class, fis, st)), newref(r, st), validfieldinits(str, fis, st) ⊦ sks0 = sk ' + sks1, sks0 = [], r0 = jvmref, r = jvmref, sk ∈ fis, dups(fis .vals .nonnullrefs), hasSharing(fis .vals .nonnullrefs, st), junkref(str, r, addobj(r, class, fis, st))
