<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">In JPA 1.0's <tt>persistence.xml</tt>, <tt><exclude-unlisted-classes></tt> defaulted to <tt>false</tt> (providers always scanned for entities). As of JPA 2.0, <tt><exclude-unlisted-classes></tt> was changed to default to <tt>true</tt>. However, Hibernate EntityManager does not honor this. See lines 219-221 of <tt>PersistenceXmlParser.java</tt>:</p>
<div class="code panel" style="border-width: 1px;; border: 1px solid #ccc; background: #f5f5f5; font-size: 12px; line-height: 1.333; font-family: monospace; border: 1px solid #ccc; -moz-border-radius: 3px 3px 3px 3px; border-radius: 3px 3px 3px 3px; margin: 9px 0">

}</pre>
</div>
</div>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">This has two consequences:</p>
<ol>
<li>
If you omit <tt><exclude-unlisted-classes></tt>, Hibernate will scan for entities, which is not compliant. Hibernate should default to the right value based on the JPA version.
</li>
<li>
If you intentionally add <tt><exclude-unlisted-classes>false</exclude-unlisted-classes></tt> to <tt>persistence.xml</tt> to enable scanning, Hibernate will disable scanning, which is downright incorrect.
</li>
</ol>
