---------------------------------------

             Summary: gremlin subgraph step fail when vertices contains properties with null
values
                 Key: TINKERPOP-2109
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-2109
             Project: TinkerPop
          Issue Type: Bug
          Components: tinkergraph
    Affects Versions: 3.3.4
            Reporter: Bruno Supiot


We are currently using OrientDB as graph database backend. OrientDB allows properties with
null values. The orientdb database is requested with Grooy/Gremlin request.

When we are requesting for a 'subgraph' step (which use the tinkergraph on memory database
for creating the subgraph), an exception is thrown when the vertex of Orientdb contains properties
with null values:

Part of the exception trace:
