how to error handling in StateMachineInterceptorAdapter override method preStateChange

[pasudo123]

Hello!

i wrote code below! with kotlin lang. i'm used preStateChange() method by implements StateMachineInterceptorAdapter<S, E> class

@Transactional
    override fun preStateChange(
        state: State<Product.Status, Product.Event>?,
        message: Message<Product.Event>?,
        transition: Transition<Product.Status, Product.Event>?,
        stateMachine: StateMachine<Product.Status, Product.Event>?,
        rootStateMachine: StateMachine<Product.Status, Product.Event>?
    ) {

        if (state.isNull()) {
            log.info("@@@ preStateChanged : state is null")
            return
        }

        log.info("@@@ preStateChanged : state.id[${state!!.id}]")

        throw RuntimeException("oops?!")
    }

i want to try/catch in preStateChange() method if throw exception

but looking at the preStateChange method does not throw and did logging and return false (boolean type)

AbstractStateMachine.java

    private boolean callPreStateChangeInterceptors(State<S,E> state, Message<E> message, Transition<S,E> transition, StateMachine<S, E> stateMachine) {
        try {
            getStateMachineInterceptors().preStateChange(state, message, transition, this, stateMachine);
        } catch (Exception e) {
            log.info("Interceptors threw exception, skipping state change", e);
            return false;
        }
        return true;
    }

// if callPreStateChangeInterceptors() method return false and switchToState() method return Mono.empty()
private Mono<Void> switchToState(State<S,E> state, Message<E> message, Transition<S,E> transition, StateMachine<S, E> stateMachine) {
        return Mono.defer(() -> {
            if (!isInitialTransition(transition) && !StateMachineUtils.isTransientPseudoState(state)
                    && !callPreStateChangeInterceptors(state, message, transition, stateMachine)) {
                return Mono.empty();
            }

can I get some help with that? (i using 3.2.0 version)

Had the same problem, Based on document, throw exception in Interceptor should stop the transaction but actually it doesn't when the transaction is happened to a Pseudo State, such as choice.
