Proof step 10 from proof is_valid_ref-putbytearray (previous step)

st[r0 -- _type] .type = mkarraytype(ty0), mkarraytype(ty0) ≤ ty ⊦ ty = mkclasstype(`java.lang.Object' .class), is_valid_ref(r0, putByteArray(bytes, r, i, st)) ∧ is_array(str, r0, putByteArray(bytes, r, i, st)) ↔ is_array(str, r0, st), is_arraytype(ty)
