Getting hibernate persistence-unit classes from both ORM and OGM - mongodb

Question

I'm trying to use both of hibernate's orm and ogm in the same application.
In my persistence.xml I have two persistence-unit:
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">
<persistence-unit name="orm-mysql">
...
<class>...</class>
...
<class>...</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
...
</persistence-unit>
<persistence-unit name="ogm-mongodb" transaction-type="JTA">
...
<class>...</class>
...
<class>...</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
...
</persistence-unit>
...
</persistence>
I want to use the hibernate orm native api with both orm and ogm, and so I need to add the annotated classes to two different MetadataSources.
Since I have the persistence units I thought that I can do this:
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("orm-mysql");
Set<ManagedType<?>> managedTypes = entityManagerFactory.getMetamodel().getManagedTypes();
for (ManagedType type : managedTypes) {
ormSources.addAnnotatedClass(type.getJavaType());
}
entityManagerFactory = Persistence.createEntityManagerFactory("ogm-mongo");
managedTypes = entityManagerFactory.getMetamodel().getManagedTypes();
for (ManagedType type : managedTypes) {
ogmSources.addAnnotatedClass(type.getJavaType());
}
The problem is that in the first iteration, of the orm classes, I get both the orm and ogm classes that are included in orm-mysql and ogm-mongo.
The second time around it's fine though, I get only the ogm-mongo classes.
Can't figure out what's wrong, any ideas?

Answer 1

In case anyone makes this stupid mistake as well, I had:
<persistence-unit name="orm-mysql">
...
<class>...</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties>
<property name="hibernate.archive.autodetection" value="class"/>
...
</properties>
</persistence-unit>
Removing the hibernate.archive.autodetection property solved the problem.
