Proof step 14:
st[r0 -- _length] = intval(i), st[r0 -- _type] = typeval(mkarraytype(byte_type)), r0 -- _type ∈ st, r0 -- _length ∈ st, is_arrayref(r0, i, st), r0 ∈ st, 0 ≤ i, ∀ j0. ¬ j0 < 0 ∧ ¬ i ≤ j0 → is_bytevalue(st[r0 -- j0 ']) ⊦ fs ' = _type, fs ' = _length, r0 = jvmref, okreftype(refval(r0), mkarraytype(byte_type), st) ∧ (0 ≤ j ∧ j < i → is_bytevalue(st[r0 -- j ']))
