Multicast communication in EPP 5 default config

Issue

• We are running a standalone JBoss EPP 5.1 instance in our development environment. The EPP instance is created using the "default" server profile. On the same network, we have another staging server with another EPP instance running.

We notice that even though clustering is not enabled at EAP level (since we are using "default" as the template), EPP 5 is still trying to form a cluster. We see messages similar to the following ones in the log file:

15:07:54,653 INFO  [RPCManagerImpl] Received new cluster view: [127.0.0.1:37378|1] [127.0.0.1:37378, 127.0.0.1:53149]
15:07:54,855 INFO  [RPCManagerImpl] Received new cluster view: [127.0.0.1:37378|1] [127.0.0.1:37378, 127.0.0.1:53149]

How can we disable multicast communication in the default configuration of EPP 5?
