Proof step 13 from proof hasSharing-dups-object (previous step)

st[r -- sk0] = st[r -- sk], sk0 ∈ instfields(st[r -- _type] .type .class), sk ∈ instfields(st[r -- _type] .type .class), is_referencevalue(st[r -- sk]), is_classtype(st[r -- _type] .type) ⊦ st[r -- sk] .refval = jvmref, sk0 = sk, r = jvmref, hasSharing(r, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 12:
st[r -- _type] .type = mkclasstype(class), st[r -- sk0] = st[r -- sk], sk0 ∈ instfields(class), sk ∈ instfields(class), is_referencevalue(st[r -- sk]), is_classtype(st[r -- _type] .type) ⊦ st[r -- sk] .refval = jvmref, sk0 = sk, r = jvmref, hasSharing(r, st)
