Proof step 166:
fis .keys = instfields(class), st[r0 -- sks0] = st[r0 -- sks], validfieldinits(str, fis, st), newref(r, st), fits(r0, sks0, st), fits(r0, sks, st), r0 ∈ fis .vals .nonnullrefs ⊦ r = jvmref, st[r0 -- sks] .refval = jvmref, sks = [], sks0 = [], sks0 = sks, junkref(str, r, addobj(r, class, fis, st)), hasSharing(r, addobj(r, class, fis, st)), dups(fis .vals .nonnullrefs)
