I just set up Arquillian+WF for running tests from hibernate-core as well as hibernate-orm-modules. The first test was org.hibernate.test.wf.ddl.WildFlyDdlTest which is an attempt to reproduce this. I was unable to. Regardless of whether there was an active transaction or not, the test succeeds in creating a schema and then dropping it via a a JTA DataSource (I tried both JTA and non-JTA).
