When applications call javax.persistence.Persistence.generateSchema() from active JTA transactions, Hibernate defaults to using org.hibernate.engine.transaction.jta.platform.internal.JBossStandAloneJtaPlatform, which uses com.arjuna.ats.jta.TransactionManager. We cannot use com.arjuna.ats.jta.TransactionManager directly anymore, instead we need to use the WildFly transaction client layer which wraps Arjuna TM.
