The simplest setup to reproduce, involves creating a JPA project (Hibernate Platform 2), and adding the following files :
{code:title=persistence.xml }
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
	<persistence-unit name="jpa">
		<class>foo.bar.model</class>
	</persistence-unit>
</persistence>
{code}

{code:package-info.java}
package foo.bar.model;
{code}
