Stephen Mallette closed TINKERPOP-2900.
---------------------------------------
Resolution: Not A Bug
{{ProductiveByStrategy}} forces a {{null}} to be returned when the property
isn't present. like sql, {{null}} has a natural sort order ahead of a value:

> Project: TinkerPop
> Issue Type: Bug
> Reporter: Lei Tang
> Priority: Major
>
> When I sort vertices with property 'vp1', I expect TinkerGraph returns
> vertices that have property 'vp1' first. However, when I turn on
> ProductiveByStrategy, it first returns vertices without property 'vp1'.

> {code:java}
> gremlin> :> g.addV().property('vp1', 11)
> ==>v[0]
> gremlin> :> g.addV().property('vp2', 'hello')
> ==>v[2]
> gremlin> :> g.withStrategies(ProductiveByStrategy).V().order().by('vp1')
> ==>v[2]
> ==>v[0] {code}
