Proof step 49 from proof junkrefs-addarray (previous step)

¬ (r ≠ jvmref ∧ (¬ is_valid_ref(str, r, st) ∨ ¬ st[r -- _type] .type ≤ ty)), junkrefs(str, r ' + acc, ty, addarray(r0, ty0, vals, st)), newref(r0, st), ∀ str, ty, r0, ty0, vals, st. junkrefs(str, acc, ty, addarray(r0, ty0, vals, st)) ∧ newref(r0, st) → r0 = jvmref ∨ junkrefs(str, acc, ty, st) ⊦ r = jvmref, r0 = jvmref, junkrefs(str, r ' + acc, ty, st)
