Using PersistenceAnnotationBeanPostProcessor in java-based config

[reardonm]

I've been working with @Configuration classes with mixed results. It seems like it should be possible to replace...

<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor">
        <property name="defaultPersistenceUnitName" value="truth" />
</bean>

with...

@Bean
    public PersistenceAnnotationBeanPostProcessor persistenceAnnotationBeanPostProcessor() { 
    	PersistenceAnnotationBeanPostProcessor proc = new PersistenceAnnotationBeanPostProcessor();
    	proc.setDefaultPersistenceUnitName("my-unit");
    	return proc;
    }

However, this seems cause existing BeanProstProcessors on the ApplicationContext to break. In my case I am using a PropertyPlaceholderConfigurer which stops working once the PersistenceAnnotationBeanPostProcessor is created. Am I missing something?

Thanks

I know this is an old thread but I ran into this same issue (using Spring 3.1.2) and it took me a while to figure out what went wrong. Is PersistenceAnnotationBeanPostProcessor necessary? I seem to run fine without it (i.e. entitymanagers are being wired up).
