JGroups cluster nodes ports if port_range set to 0 or default value

Question

I would like to know if the JGroups cluster uses the next available port, even if the port_range is set to 0 or allowed to remain at the default value. As per documentation, I understand, number of additional ports to be probed for membership will not be probed if port_range is set to 0. Will it be the same if no value is set for port_range and bind_port is set to a specific port, for JGroups TCP_PING?

Thanks, Nivedita

If you set bind_port to 7800 and port_range is 0 in TCP, then port 7800 will be taken. If already taken by a different process, an exception will be thrown and the node won't start.
