I got janusgraph 0.4.0
apache.tinkerpop.gremlin 3.4.2
com.github.jespersm.spring-data-gremlin 1.0.0-SNAPSHOT
and Widnows 10
And i try to run such a test
Graph graph = JanusGraphFactory.open("inmemory");
graph.traversal()
.addV("Org").iterate();
graph.traversal().tx().commit();
And thats all
when i run this test (or any tests where is JanusGraphFactory.open and tx().commit() after that), i get this exception

I was triyng everything!
Please, somebody, do you know the answer???
Its a VERY strange problem...
I was running into a similar issue and it looks like the config option graph.timestamps can be set in the config file.
If you were to create the graph like:
Configuration conf = new PropertiesConfiguration(propertiesFileName);
Graph graph = GraphFactory.open(conf);
In the file referenced by propertiesFileName, you can set the config option like this:
graph.timestamps=NANO
That solved my issues on Windows.
