     *
     * There's no sane way to do this in a single query with JPA 2.1, it appears: JPA doesn't

     * we're ready to return the result). This is bad and dumb but I can't find a better working
     * alternative.
     *
     * (I'll just note that I did also try JPA/Hibernate native SQL queries but couldn't get the
     * joins or fetch groups to work with them.)
     *
     * If we want to fix this, we need to move identifiers out entirely to separate tables:
     * BeneficiaryHicns and BeneficiaryMbis. We could then safely query these tables and join them
