Traversing issue Similar to #1738 is noticed with OrientDB Version 2.0.4
There seems to be an issue with lazy loading data when using
GremlinPipeline with OrientDB. When run from command line, only immediate
edge is retrieved. But in eclipse debugger, when stepped through
gremlinpipeline code, all the edges are retrieved.
Sample Graph
1 --> 2 --> 3 --> 4 --> 5 --> 6
For given vertex 1, i want to retrieve vertices 2,3,4,5,6
