Stephen Mallette updated TINKERPOP-2499:
----------------------------------------
Description:
This issue comes from TINKERPOP-2481 where it was originally noted that perhaps
{{IdentityRemovalStrategy}} had something to do with the following:
{code}
gremlin> g.V().match(__.as("a").out("knows").as("b")).unfold()
gremlin> g.V().match(__.as("a").out("knows").as("b")).identity()
==>[]
==>[]
gremlin>
g.withStrategies(IdentityRemovalStrategy.instance()).V().match(__.as("a").out("knows").as("b")).identity()
==>[a:v[1],b:v[2]]
==>[a:v[1],b:v[4]]
gremlin>
g.withoutStrategies(PathRetractionStrategy).V().match(__.as("a").out("knows").as("b")).identity()
==>[a:v[1],b:v[2]]
==>[a:v[1],b:v[4]]
{code}
but it is not a good idea to fix the behavior of one strategy by way of another
so {{PathRetractionStrategy}} needs to get a bit smarter.
