     [ https://issues.apache.org/jira/browse/TINKERPOP-1323?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Marko A. Rodriguez closed TINKERPOP-1323.
-----------------------------------------
       Resolution: Fixed
         Assignee: Marko A. Rodriguez
    Fix Version/s:     (was: 3.1.3)

This is only fixed in 3.2.1 because that is where all the new work on {{TraversalHelper.isLocalStarGraph()}} was done.

> A nested {{match()}} can leave the star-graph w/o the compiler complaining about it; this ultimately leads to a {{RuntimeException}}. The most simple query to reproduce it:
> {code}
> g = TinkerFactory.createModern().traversal().withComputer()
> g.V().filter(match(
>     __.as("project").in("created").as("person"),
>     __.as("person").values("name").as("name")
>   ))
> {code}
> Of course the filter step is pointless in this example, but that's the easiest way to reproduce it.
