Proof step 17:
st[r0 -- _length] = intval(i), st[r0 -- _type] = typeval(mkarraytype(ty0)), r0 -- _length ∈ st, 0 ≤ i, r0 ∈ st, r0 -- _type ∈ st, ty0 ≤ ty, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → r0 -- j ' ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r0 -- j '], ty) ⊦ r0 = jvmref, r = r0, okreftype(refval(r0), mkarraytype(ty), st) ∧ (0 ≤ j ∧ j < i → r0 -- j ' ∈ st) ∧ (0 ≤ j0 ∧ j0 < i → okval(st[r0 -- j0 '], ty))
