Hi to all,

in my vertex centric iteration I get the following exception, am I doing something wrong or is it a bug of Gelly?

starting iteration [1]:  CoGroup (Messaging) (6/8)

IterationHead(WorksetIteration (Vertex-centric iteration (test.gelly.functions.VUpdateFunction@1814786f | test.gelly.functions.VMessagingFunction@67eecbc2))) (4/8) switched to FAILED with exception.
