Proof step 27 from proof hasSharing-pathex (previous step)

(refs1 + r0 ') .first = st[r -- fs '] .refval, is_obj(str, r, st), hasSharing(r0, st), fs ' ∈ instfields(st[r -- _type] .type .class), is_referencevalue(st[r -- fs ']), validrefs(str, refs1 + r0 ', fs .type, st), ∀ st, r, str, refs. # refs < # (refs1 + r0 ') → (validrefs(str, r ' + refs, st[r -- _type] .type, st) ∧ hasSharing(refs .last, st) → refs = [] ∨ hasSharing(r, st)) ⊦ r = jvmref, hasSharing(r, st)
