Proof step 35 from proof validrefs-addobj-notin (previous step)

¬ (r0 ≠ jvmref ∧ (¬ is_valid_ref(str, r0, st) ∨ ¬ st[r0 -- _type] .type ≤ ty)), validrefs(str, r0 ' + acc, ty, st), ∀ str, ty, st, r, class, fis. validrefs(str, acc, ty, st) → r ∈ acc ∨ validrefs(str, acc, ty, addobj(r, class, fis, st)) ⊦ r0 = jvmref, r = r0, validrefs(str, r0 ' + acc, ty, addobj(r, class, fis, st)), r ∈ acc
