[werkflow-user] Hanoi example failure

Hi,

I recently checked out werkflow-core and ran the maven:werkflow-hanoi
target. After passing all the tests, the example ran through but threw
an Exception part way.

Can anyone tell me if I've got something misconfigured?

Many thanks.

Peter

The output was :
