    await().untilTrue(added);
    // TODO see above we can remove this once we can await DataBroker listeners
    // The sleep () is required :( so that the throw new IllegalStateException really leads to an ERROR log,
    // because the (easily) await().untilTrue(...) could theoretically complete immediately after added.set(true)
    // but before the throw new IllegalStateException("TEST") and LOG.  To make this more reliable and without sleep
    // would require more work inside DataBroker to be able to await listener event processing.
