Hi, I created a persistence.xml file with the definition of two persistence units: one with JTA (for EE components) and one with RESOURCE_LOCAL (for JUnit testing). When deploying the application fails saying that I didn't define a non-jta-data-source for the RESOURCE_LOCAL, but the fact is that since this p.u is for JUnit I didn't define a datasource at all, but just properties to connect to the database. This issue deemed to be already resolved in 4.2.0-CR2, as stated here: http://jira.jboss.com/jira/browse/EJBTHREE-433 However I'm running 4.2.0-GA and it's still there.
