Proof step 20 from proof okbytearray-validref (previous step)

st[r -- _length] = intval(i), is_referencevalue(refval(r)) ∧ ( refval(r) .refval ≠ jvmref → refval(r) .refval -- _type ∈ st ∧ is_typevalue(st[refval(r) .refval -- _type]) ∧ st[refval(r) .refval -- _type] .type ≤ mkarraytype(byte_type)), r -- _length ∈ st, is_arrayref(r, i, st), junkref(str, r, st), r ∈ st, 0 ≤ i, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → is_bytevalue(st[r -- j ']) ⊦ r = jvmref, is_array(str, r, st)

Proof step 19:
st[r -- _length] = intval(i), st[r -- _type] .type = mkarraytype(byte_type), r -- _length ∈ st, is_arrayref(r, i, st), junkref(str, r, st), r ∈ st, 0 ≤ i, r -- _type ∈ st, is_typevalue(st[r -- _type]), ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → is_bytevalue(st[r -- j ']) ⊦ r = jvmref, is_array(str, r, st)
