And obtained the following new goals

Proof step 12:
st[r -- mkfs(class, ty0, fieldvar) '] = refval(r0), mkfs(class, ty0, fieldvar) ' ∈ instfields(st[r -- _type] .type .class), validrefs(str, r0 ' + refs1, ty0, st[r -- sk, val]), is_obj(str, r, st), is_valid_ref(r, st), is_obj(str, r, st[r -- sk, val]), st[r -- _type] .type ≤ ty ⊦ mkfs(class, ty0, fieldvar) ' = sk, sk = _length, sk = _type, r0 = st[r -- sk] .refval, val .refval = r0, r = r0, r = jvmref, r0 ∈ refs1, dups(refs1), r ∈ refs1, validrefs(str, r0 ' + refs1, ty0, st)
