[Hawkular-dev] logging in java agents is not trivial in WildFly / EAP

[Jan Martiška]

>From the log you attached it seems you are adding the agent to a managed
server, not the host controller. Can you try adding these three settings to
the managed servers' JVM configuration? AFAIK this needs to be done for the
boot class loader to be able to access the logmanager... I know especially
the second one is ugly but I'm not aware of a better solution at the moment

-Djboss.modules.system.pkgs=org.jboss.byteman,org.jboss.logmanager
-Xbootclasspath/a:modules/system/layers/base/org/jboss/logmanager/main/jboss-logmanager-2.0.7.Final-redhat-1.jar
-Djava.util.logging.manager=org.jboss.logmanager.LogManager
