Exception while using drools-persistence-jpa persistence in Fuse

Issue

We are using drools-persistence-jpa (6.2.0.Final-redhat-4) and Fuse 6.2.0. The java code which we are using to persist kiesession is

protected void createSession(String kb) {
   try{
    KieServices kieServices = KieServices.Factory.get();
    KieContainer kieContainer = kieServices.newKieClasspathContainer(getClass().getClassLoader());
    KieBase kbase = kieContainer.getKieBase(kb);
    Environment env = kieServices.newEnvironment();
    JtaTransactionManager droolsJTATxMgr = new JtaTransactionManager(userTransaction, null, jtaTransactionManager);
    EntityManagerFactory entityManagerFac = Persistence.createEntityManagerFactory("com.sample");
    env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, entityManagerFac);
    env.set( EnvironmentName.TRANSACTION_MANAGER, droolsJTATxMgr);
    System.out.println(env.get(EnvironmentName.ENTITY_MANAGER_FACTORY));
    JpaPersistenceContextManager jpaPersistenceContextManager = new JpaPersistenceContextManager(env);
    env.set( EnvironmentName.PERSISTENCE_CONTEXT_MANAGER, jpaPersistenceContextManager);
    session = kieServices.getStoreServices().newKieSession(kbase, null, env);
    int sessionId = session.getId();
    System.out.println(sessionId);
}catch(Exception ex){}

We are trying to persist kiesession in the database using openjpa (2.3.0) and getting the below error.

Caused by: <openjpa-2.3.0-r422266:1540826 fatal user error> org.apache.openjpa.persistence.ArgumentException: "
.WorkItemInfo.workItemId" declares generator name "workItemInfoIdSeq", but uses the AUTO generation type.  The only valid generator names under AUTO are "uuid-hex" and "uuid-string".
