IndexOutOfBoundsException when restoring form the database #1057

Open AbstractAlao opened 2 years ago

AbstractAlao commented 2 years ago

I am adding items to the extended state like so:

public void updateLoanProcessor(StateMachine<LoanEventStatus, LoanEventAction> stateMachine, LoanProcessor processor) {
        stateMachine.getExtendedState().getVariables().put(StateManager.PARAM_PROCESSOR, processor);
    }

When I reboot my service and try to acquire the state machine, I get the following error:

I'm not sure if it's because I added new properties to my class object.

Same issue here. I don't know if there is a most recent Kyro version to provide a better approach ignoring properties that don't exist in serialized data.
