Fail to load network of broker configuration

[enzdal]

Describe the bug
Hi, we are configuring the brokers to have more replicas. We tried to use the configuration as suggested in the comments of the activemq.xml file but we are getting an error while parsing the xml.

To Reproduce
Steps to reproduce the behavior:

1. Go on activemq.xml file, uncomment the section
2. run an instance of broker

Expected behavior
The broker should start and connect to the other nodes.

Version of Kapua
latest development

Type of deployment
[ ] Docker
[ ] Openshift (in its variants)
[ ] Others
[x] Kubernetes

Main component affected
[ ] Console (in case of console please report info on which browser you encountered the problem)
[ ] REST API
[x] Message Broker
[ ] - Others

The error:
