Proof step 15 from proof validsubset-put-statfield (previous step)

⊦ (∀ r, ty. validref(str, r, ty, st) → validref(str, r, ty, st0)) ∧ (∀ r. ¬ r ∈ st ∧ (r = jvmref ∨ r ∈ st0) → ¬ junkref(str, r, st0[jvmref -- sk, val])) ↔ (∀ r, ty. validref(str, r, ty, st) → validref(str, r, ty, st0)) ∧ (∀ r. ¬ r ∈ st ∧ r ∈ st0 → ¬ junkref(str, r, st0))
