> The following code:

>     MapVector vector = new MapVector(name, allocator, null);
>     ComplexWriterImpl mapWriter = new ComplexWriterImpl("colMap", vector);
>     BaseWriter.MapWriter mapWr = mapWriter.rootAsMap();
>     // write into the map vector
>     …
>     mapWriter.setValueCount(5);
> {code}
> is expected to set the value count of _vector_ to 5, but it doesn't
