// Why these packages?
// 1) msc, dmr, controller.client are part of the StandaloneServer API

// 4) org.jboss.logging and org.jboss.logmanager -- logmanager.LogManager is installed as
// the JDK log manager, and it uses its LogContext class and the static field therein
// heavily. If the CLI-side LogContext class and the modular side LogContext class are different,
// nothing works properly. Since logmanager is a system pkg, the org.jboss.logging API stuff must be too
