Customer Miro reported below:
'I started writing a basic "mocked up" data migration based on the "Money transfer project" and the Java SDK documentation. Its been going slowly since I got stuck on the problem below, unfortunately. The problem I hit was related to serialization/deserialization and is lightly documented (and not included in any of the examples). This is as simple as forgetting to create a default constructor on say an input parameter. If this happens the test just hangs forever.'

Describe the solution you'd like
