Hi Mahesh Babu,

I had similar problem that your (java.lang.IllegalArgumentException:
Messages must never be behind the vertex in ID! Current Message ID: 2 vs. 20
). In my case the problem was that I tried to send a message to a vertex
that was not created. This model of message passing scales better for
undirected graphs. I solved this problem by writing a converter that
converts directed graphs to undirected graphs.
