When switching dao.framework to JPA running web tests and the war with jetty:run-war results in a StackOverflowException because of a bug present in the version of Xerces included in Maven.

The problem is documented with a resolution in the Spring AbstractJpaTests javadoc here:

  http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/test/jpa/AbstractJpaTests.html

So everything works adding an updated dependency for xerces:

 <dependency>
   <groupId>xerces</groupId>
     <artifactId>xercesImpl</artifactId>
   <version>2.8.1</version>
 </dependency>
