How do you add that argument with docker? 
I tried with the $JAVA_OPTS env variable but it fails saying my logging properties are not what they should:

WFLYLOG0078: The logging subsystem requires the log manager to be org.jboss.logmanager.LogManager. The subsystem has not be initialized and cannot be used. To use JBoss Log Manager you must add the system property "java.util.logging.manager" and set it to "org.jboss.logmanager.LogManager"

Do you have any ideas?
