> Adding a transformer is unnecessary if classes are enhanced at build time. As far as I can tell, you specify this by adding the <exclude-unlisted-classes> property to persistence.xml. This could probably be made more clear by calling the property something like "build-time-enhancement-only" or "disable-runtime-enhancement". Additionally, this causes a Spring configured JPA to fail with and IllegalStateException if no LoadTimeWeaver is specified in the LocalContainerEntityManagerFactory. The relevent code is on line 93 of PersistenceProviderImpl
>     public EntityManagerFactory createContainerEntityManagerFactory(
>         PersistenceUnitInfo pui, Map m) {
>         PersistenceProductDerivation pd = new PersistenceProductDerivation();
>         try {
>             ConfigurationProvider cp = pd.load(pui, m);
>             if (cp == null)
>                 return null;
>             // add enhancer
>             String ctOpts = (String) Configurations.getProperty
>                 (CLASS_TRANSFORMER_OPTIONS, pui.getProperties());
>             pui.addTransformer(new ClassTransformerImpl(cp, ctOpts, 
>                 pui.getNewTempClassLoader()));
>             BrokerFactory factory = Bootstrap.newBrokerFactory(cp, 
>                 pui.getClassLoader());
>             return OpenJPAPersistence.toEntityManagerFactory(factory);
>         } catch (Exception e) {
>             throw PersistenceExceptions.toPersistenceException(e);
>         }
>     }
