I'm struggling to understand a problem I'm seeing with Spring Data JPA when I try and run a test with Gemini JPA.
The getMetamodel() method of EntityManagerFactory returns null, causing an exception within SD JPA. If I run my test outside of the OSGi server (Virgo) using a LocalContainerEntityManagerFactoryBean, everything works fine.
I can also create a working OSGi bundle which contains a manually created DAO (without Spring Data JPA involved) with the EM provided by Gemini JPA. But, for some reason, I can't combine the two approaches and I've been tearing my hair out trying to understand what's going on.
When testing with the local EM I didn't have any metamodel classes in my project (I'm not working on anything of my own that requires them) and things worked. I've since generated these classes within my persistence unit (separate bundle) but it hasn't resolved the issue with Spring Data JPA.
I'm using Virgo 3.6, and Gemini JPA 1.1. with Gemini DBAccess and MySQL.
Can anyone suggest how I can debug this further?
Here's the error from Virgo:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'testDAO': Injection of persistence dependencies failed; nested exception is java.lang.IllegalArgumentException: JPA Metamodel must not be null!

Here's my bundle-context.xml:

Do I need to declare a "org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" bean? I've tried with and without but it doesn't change the error I'm getting.
