> [Java] Minor types don't account for nullable FieldType flag

>                 Key: ARROW-999

>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: Java
>    Affects Versions: 0.3.0

> Calling e.g. `FLOAT4.getNewVector("foo", new FieldType(false, ...), ...)" 
> returns a NullableFloat4Vector instead of a Float4Vector.
> edit: Float4Vector doesn't implement FieldVector, so can't currently be a 
> top-level vector. I'm confused as to what the nullable flag is supposed to 
> represent then.
