In stateful ejb session Bean1 I have reference on another stateful ejb session Bean2 ? bean2Ref.
I can correctly call any method from bean2Ref until calling processOrder from that bean that rises exception during data flushing to database.

This is definition of processOrder() method in Bean2

@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
 public void processOrder() {
 //? some code
 }

This code fragment from method in Bean1

 bean2Ref.startProcessing();
 try {
 bean2Ref.processOrder(saveTry);
 } catch(Exception ex) {
 log.error("error - " + ex.getMessage());
 }
 bean2Ref.finalProcessing();

Calling bean2Ref.finalProcessing() (and any other from bean2Ref) will rise exception ?Could not find Stateful bean: 5c4o11h-844ahm-ek9u3vhm-1-ek9vq78r-3b?

Is it correct behaviour of ejb3 container? Is it possible to save bean2Ref instance?
