Unable to get TransactionAttributeType SUPPORTS working

[thhal]

I have a stateless session bean with a method that creates a query using the entity manager. Since the method is read-only I don't want to force a new transaction so I use the attribute type SUPPORTS. I can't get that to work. I always get the following stack trace:

javax.persistence.TransactionRequiredException: EntityManager must be access within a transaction
at org.jboss.ejb3.entity.ManagedEntityManagerFactory.getSession(ManagedEntityManagerFactory.java:124)
at org.jboss.ejb3.entity.InjectedEntityManager.getSession(InjectedEntityManager.java:154)
at org.jboss.ejb3.entity.InjectedEntityManager.createQuery(InjectedEntityManager.java:67)
...

Why is that? Do I always have to have a transaction? Even if the operation is just read-only?

TIA

Anyone out there that knows the answer to this question? Is it a bug in the EJB 3.0 EntityManager implementation? Should I file a JIRA on it?
