It does work for vertices built by the java code examples:

I think you're running afoul of the TinkerGraph's id manager:

gremlin> graph = TinkerGraph.open()

==>tinkergraph[vertices:0 edges:0]

gremlin> g = graph.traversal()

==>graphtraversalsource[tinkergraph[vertices:1 edges:0], standard]

gremlin> graph.addVertex(T.label,'boom','bId',5)

==>v[0]

gremlin> g.V(0)

gremlin> g.V(0L)

==>v[0]

You can read more about how to set that up better to suit your identifier needs here:

Yes, so it is. Thank you. While it's handy to know this, TinkerFactory.createClassic() still uses Integers which I think would be more intuitive for the casual user. Perhaps that would be a better default for all TinkerGraph in-memory graphs.  I would think that a user needing to load more than 2 billion elements would be considered more of an advanced user and at that point would need to dig into the docs to tweak the properties. But then again, since I'm the only one complaining, maybe I'm the minority.  Thanks again!

I've also been wondering if the default configuration should come with id managers already set. "0L" might not be recognizable by non-java users and is a little tricky with json serialization so this config documentation is kind of a mandatory stop for these use cases.

There's a reason why it's defaulted but I don't remember what it is :( There's also a ticket to improve consistency around identifiers in TinkerGraph but the solution doesn't seem to be possible without breaking change if I remember correctly. The JSON serialization and type lossiness should be less of a problem with GraphSON 2.0 which should come as part of 3.2.1.
