Wes McKinney commented on ARROW-1837:
-------------------------------------
Since Java doesn't have unsigned integer values, I presume that we'll want to
return them in {{getObject}} as a larger signed integer object for now – as
long as unsigned values sent from other applications can be understood
correctly. So a {{UInt2Vector}} would return {{int}} values, {{UInt4Vector}}
return {{long}} values, and so forth (would {{UInt8}} have to return
{{BigInteger}}?)
> [Java] Unable to read unsigned integers outside signed range for bit width in
> integration tests

> the error from us
