[ https://jira.jboss.org/jira/browse/JGRP-875?page=com.atlassian.jira.plugi... ] Bela Ban commented on JGRP-875: ------------------------------- This entails a change in behavior: - When a variable is used in the XML config, e.g. value="${var:1000}", and 'var' is defined as a system property (900 for example), it will substitute the value defined in the config, so the value used will be 900 here. - We'll only overwrite values that have a variable in the config, which can be replaced. In the following case: value="1000", even if -Dvar=900 is defined, we do *not* overwrite 1000 ! - So the biggest change is this: using -Djgroups.bind_addr=1.2.3.4 does *not* necessarily overwrite bind_addr in the config file ! NO: bind_addr="5.5.5.5". The bind address will be 5.5.5.5 ! YES: bind_addr="${jgroups.bind_addr:5.5.5.5}": the bind address will be 1.2.3.4 ! -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
