> Integration testing exposed a bug in cases where values_data.len() is zero. This fails with divide by zero error.
> {code:java}
> // check that values_data length is multiple of len
> assert!(
>     values_data.len() / len == self.list_len as usize,
>     "Values of FixedSizeList must have equal lengths, values have length {} and list has {}",
>     values_data.len(),
>     len
> ); {code}
