-<p>DataNucleus's persistence-by-reachability algorithm adds the
<code>AgreementRole</code>s into a <code>SortedSet</code>, which causes
<code>AgreementRole#compareTo()</code> to fire:
-* the evaluation of the "agreement" property delegates back to the
<code>Agreement</code>, whose own <code>Agreement#compareTo()</code> uses the
scalar <code>reference</code> property. As the <code>Agreement</code> is
already in-memory, this does not trigger any further database queries
-* the evaluation of the "startDate" property is just a scalar
-* the evaluation of the "party" property delegates back to the
<code>Party</code>, whose own <code>Party#compareTo()</code> requires the uses
the scalar <code>reference</code> property. However, since the
<code>Party</code> is not yet in-memory, using the <code>reference</code>
property triggers a database query to "rehydrate" the <code>Party</code>
instance.</p>

<p>In other words, in figuring out whether <code>AgreementRole</code> requires
the persistence-by-reachability algorithm to run, it causes the adjacent
associated entity <code>Party</code> to also be retrieved.</p>
