I assume in your second thread that you call factory.getTx() before calling
graph.addVertex() and graph isn't cached beforehand.
Is that accurate?
You said that if you restart the application it works. Do you mean if you
restart the application and just execute the second thread's task (in other
words you're not calling alter class again)?
Just trying to clarify the situation.
Thanks,
