When using a <literal>Date</literal>, instead of a <literal>long/Long</literal> for the revision timestamp,
take care not to use a mapping of the property which will loose precision (for example, using
<literal>@Temporal(DATE)</literal> is wrong, as it doesn't store the time information, so many of your
revisions will appear to happen at exactly the same time). A good choice is a
<literal>@Temporal(TIMESTAMP)</literal>.
