Since I started using openJKD 12.0.2 and Netbeans 11.1 i get this exception after creating the entities with netbeans.
If I choose in the project properties source/binary format jdk8 works fine! with source/binary format jdk9 and above i get the exception!
package tesyapp;
import Model.Testtable;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;

public class TesyApp {
public static EntityManager em;
/**

public static void main(String[] args) {
//String PERSISTENCE_UNIT_NAME = "TestAppPU";
//ClassLoader cL = Activator.class.getClassLoader();
//Map<String, Object> properties = new HashMap<>();
//properties.put(PersistenceUnitProperties.CLASSLOADER, cL);
//properties.put(PersistenceUnitProperties.ECLIPSELINK_PERSISTENCE_UNITS, PERSISTENCE_UNIT_NAME);
//create the data base ...
EntityManagerFactory emf;
Testtable tt;
System.out.println("Creating the Factory...");
emf = Persistence.createEntityManagerFactory("TestAppPU"); //, properties);
em = emf.createEntityManager();
em.getTransaction().begin();
tt = new Testtable(3);
tt.setField1("F1");
tt.setField2("F2");
em.persist(tt);
em.getTransaction().commit();
em.close();
emf.close();
}
}

How do I overcame this Exception and use openjdk with netbens 11 in order to upgrade excisting java project written in netbeans 8 with jdk8
