If I modify the datatype of TEST_NUMBER column to integer, I have the next error : 15:14:04,062 WARN [ServiceController] Problem starting service persistence.units:ear=deja10ans.ear, | unitName=deja10ans | javax.persistence.PersistenceException: org.hibernate.HibernateException: Wrong column type: TEST_TEXT, expected: varchar(255) | at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:698) | | at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:127) | at org.jboss.ejb3.entity.PersistenceUnitDeployment.start(PersistenceUnitDeployment.java:264) And this was working great on 1.1.6, again and again !
