Corey Puffalt commented on HHH-7312:
------------------------------------

Steve, is your only contention the fact that this is classed as a bug and not a feature?  Are there other issues with the pull request by Stefan?  I was just trying to implement multi-tenancy in a EJB/JPA application on JBoss 7 and couldn't find a way to achieve that without a fix like this.  Am I missing something?

> I tried to use db schema based multi tenancy with hibernate jpa / entitymanager. I use the following properties in persistence.xml:
> <property name="hibernate.multiTenancy" value="SCHEMA"/>
> <property name="hibernate.tenant_identifier_resolver" value="com.xoricon.persistence.bo.multitenancy.test.SchemaBasedTenantResolver"/>
> <property name="hibernate.multi_tenant_connection_provider" value="com.xoricon.persistence.bo.multitenancy.test.SchemaBasedMultiTenantConnectionProvider"/> 
> Both instances (SchemaBasedTenantResolver / SchemaBasedMultiTenantConnectionProvider) will be instantiated by hibernate. 
> When i call:
>   EntityManagerFactory lEntityManagerFactory= Persistence.createEntityManagerFactory("orm1");
>   EntityManager lManager = lEntityManagerFactory.createEntityManager();
> I get:
> System.out: SchemaBasedMultiTenantConnectionProvider.getAnyConnection()
> System.out: SchemaBasedTenantResolver.<init>()

> In System.out "SchemaBasedTenantResolver.<init>()" shows, that my CurrentTenantIdentifierResolver has been instantiated. But Hiberante did not call method "public String resolveCurrentTenantIdentifier()". 
> I expect, that Hibernate uses the CurrentTenantIdentifierResolver to get the current tenant id. 
> In JPA i cannot set the tenant on the Session, because the exception above occures before Session has been created. I can access the Session only by EntityManager.getDelegate(). But as shown above, i cannot create an EntityManager instance.
