  - Ensure Jersey is initialised before AAA-Shiro

    When we group the Jersey bundles with bundles using them, we run into
    initialisation races where AAA-Shiro ends up trying to use Jersey
    before the latter’s activators have run.

    All credit to Robert Varga for figuring out that we need an ordering
    constraint between Jersey as a whole and the rest of AAA-Shiro. The
    new odl-aaa-jersey-1 feature will eventually be replaced by ODL
    Parent’s odl-jersey-1 feature, once we’ve added jersey-client to
    that.
