[jboss-jira] [JBoss JIRA] (JGRP-2166) Attributes should also be set via environment variables

[Bela Ban (JIRA)]

     [ https://issues.jboss.org/browse/JGRP-2166?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bela Ban updated JGRP-2166:
---------------------------
    Description: 
Currently, an attribute such as {{mcast_port=$\{my.mcast_port:7500\}}} is set to 7500 by default. If there is a system property {{my.mcast_port}}, it will override the port.

We should also look for environment values; the precedence would be

* If there is a system property, use it
* If not, if there is an environment variable, use it // this is new
* Else use the configured value (e.g. 7500)

  was:
