Proof step 36 from proof junkrefs-put-statfield (previous step)

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