Bela Ban commented on JGRP-459:
-------------------------------

This attribute works only if you're the first member of a cluster. I've been wanting to remove this attribute for quite some time, and now I'll finally deprecate it. Reason: this forces JGroups into a client-server mode, and that's not right as JGroups is peer-to-peer.

> We've got the following scenario: three applications, App1, App2, and App3. We want App3 to be the coordinator when the apps first start, so there is no confusion about multiple groups / coordinators. So, we set App1 and App2's disable_initial_coord = true, and App3's disable_initial_coord=false. 
> Then we start App1, and it will wait. Then we start App2, and App1 / App2 will determine a coordinator, even though disable_initial_coord is set to true for both, and we have not started App3 yet! This seems to conflict with the documentation which states: 
> Note that - if a member is started as first member of a group - but its property is set to true, then it will loop until another member whose disable_initial_coord property is set to false, is started. 
> We need disable_initial_coord to work as documented.
