It is not possible to set jboss.modules.system.pkgs per server in domain mode ----------------------------------------------------------------------------- Key: WFCORE-1703 URL: https://issues.jboss.org/browse/WFCORE-1703 Project: WildFly Core Issue Type: Bug Components: Domain Management Affects Versions: 2.2.0.Final Reporter: Bogdan Ilchyshyn Priority: Minor It is not possible to set {{jboss.modules.system.pkgs}} property per server / server group in domain configuration. Even when the following configuration is added to {{host.xml}}: {code:xml} <server name="server-one" group="main-server-group"> <jvm name="default"> <jvm-options> <option value="-Djboss.modules.system.pkgs=my.package"/> ... {code} It is overridden by configuration in {{domain.conf}}: {noformat} JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true" {noformat} This is an issue for configuring third-party java agents per-server. A problem described in WFLY-895 adds to this. One should either add a whole bunch of things to _all_ jvms in domain in order to make agent work, or remove config from {{domain.conf}} to avoid overrides.
