Since the creation of the Petals Registry Overlay, it is required to start it as another system process before to start Petals ESB nodes.
It's not really user friendly for a standalone topology, or for the default/sample configuration.
The solution: the Petals Registry Overlay is embedded as a Petals ESB extension, and loaded by the Petals ESB container:
- if the topology is a standalone topology
- no configuration about the registry is set
So it is not needed to start the Petals Registry Overlay as another system process
