spring - Drools 6.2.0.Final: EntityManager is closed -

-

migrating drools 6.2.0.final v5, having issues jpa persistence. environment: jta transactions managed spring.

environment configuration:

// transaction manager spring jtatransactionmanager. seems activate kiespringtransactionmanager/kiespringjpamanager env.set(environmentname.transaction_manager, transactionmanager); env.set(environmentname.entity_manager_factory, entitymanagerfactory);

it seems triggerupdatetransactionsynchronization.beforecompletion() method accesses entitymanager retrieve objects session. however, entity manager has been closed spring in it's own beforecompletion transaction synchronization, hence exception.

is normal behavior? doing wrong?

any appreciated.

exception:
