/**
 * Pins the one case where a `remote` section is read as saying nothing.
 *
 * Whether a policy restricts addresses is settled by asking it about an address reserved for documentation, which
 * a policy granting every address matches as readily as one with no `remote` section at all. The two are the same
 * instruction written differently, and both leave `remote-access-allowed` to answer, which is the stricter
 * reading. An operator who meant every address says so with the property.
 *
 * If Jolokia ever exposes its network checker, or whether the section is present, this becomes exact and the
 * `10.0.0.1` assertion below flips.
