/**
 * Overrides the parent method while still invoking it. Since
 * {@link #isContainerActive(ContainerId)} method is also overridden here and
 * always returns 'false' the super.launchContainer(..) will only go through
 * the prep routine (e.g., creating temp dirs etc.) while never launching the
 * actual container via the launch script. This will ensure that all the
 * expectations of the container to be launched (e.g., symlinks etc.) are
 * satisfied. The actual launch will be performed by invoking
 * {@link #doLaunch(Container, Path)} method.
