Describe the bug
Logs are showing an invalid error when doing user local transaction management and committing a transaction. Does not happen in 1.2.0.CR1 but does on 999-SNAPSHOT
2020-01-24 16:09:46,216 WARN [io.agr.pool] (executor-thread-27) Datasource '': Closing open connection prior to commit

Expected behavior
This should not be logged

Actual behavior
Logs show:
2020-01-24 16:09:46,216 WARN [io.agr.pool] (executor-thread-27) Datasource '': Closing open connection prior to commit

To Reproduce
Steps to reproduce the behavior:

1. Run an app that uses resource local transactions. E.g.

@path("/hello1")
@RequestScoped
public class GreetingResource1 {

@Inject
EntityManagerFactory myEmf;

@GET
@Produces(MediaType.TEXT_PLAIN)
public String hello() {
    
    EntityManager em = myEmf.createEntityManager();
    em.getTransaction().begin();
    em.createNativeQuery("SELECT 1").getResultList();
    em.getTransaction().commit();
    em.close();
    
    return "hello1";
}

}
2) Call the rest endpoint and the logs will show the warnng when the line "em.getTransaction().commit();" is called
