> gremlin-server GraphSON serializer issue with tree()
> ----------------------------------------------------

> Key: TINKERPOP-732
> URL: https://issues.apache.org/jira/browse/TINKERPOP-732
> Project: TinkerPop
> Issue Type: Improvement
> Components: io
> Affects Versions: 3.0.2-incubating

> When using the {{tree()}} step with a GraphSON serializer the server hangs
> (though I've seen some form of serialization errors in more complex scenarios
> over titan).
> The following works fine in the console but fails using the graphSON
> serializer:
> {code:java}
> g.V(1).repeat(out()).until(out().count().is(0)).tree() // fails with .next()
> as well
> {code}
> The following works without a problem though:
> {code:java}
> g.V(1).repeat(out()).until(out().count().is(0))
> {code}
> Here's the configuration file I use for these tests:
> {code}
