I'm trying to do exactly that, but can't for the life of me get the
EntityManagerFactory to create. It fails with:

Caused by: javax.persistence.PersistenceException: No Persistence provider for EntityManager named XXXXX

Before that, I also see this warning even if I explicitly pass the suggested provider as a property:

17:43:57,250 WARN  [org.hibernate.ejb.HibernatePersistence] (default task-53) HHH015016: Encountered a deprecated javax.persistence.spi.PersistenceProvider [org.hibernate.ejb.HibernatePersistence]; use [org.hibernate.jpa.HibernatePersistenceProvider] instead.

The persistence.xml is in META-INF. I also tried META-INF/classes/META-
INF.

My init code:

	private void lazyInit() {
		Map<String, Object> props = new HashMap<>();
		props.put(AvailableSettings.PROVIDER, "org.hibernate.jpa.HibernatePersistenceProvider");
		props.put(AvailableSettings.TRANSACTION_TYPE, "RESOURCE_LOCAL");
		props.put("jboss.as.jpa.managed", "false");
		emFactory = Persistence.createEntityManagerFactory("XXXXX", props);
	}

This same persistence unit works just fine when bundled on it's own
within a normal JEE EAR.

Any idea what I'm doing wrong? Keycloak 1.7.0.Final
