Hibernate/JPA not validating against DB schema on startup

Question

For some reason hibernate is not catching issues like mapping entities to tables that do not exist. My persistence.xml file looks like this...

<?xml version="1.0" encoding="UTF-8" ?>
<persistence 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_1_0.xsd" version="1.0">

Try adding the property "hibernate.hbm2ddl.auto" with value of "validate":

<property name="hibernate.hbm2ddl.auto" value="validate"/>
