Thanks for filing this bug @e-sen. I've tested this out locally as well and ended up to the same conclusion as you've described.
I'll ensure we'll fix this issue ASAP.

Regarding your demo project by the way, I would encourage to put the @CommandHandler annotation directly on your Aggregate. This will alleviate the necessary boiler plate code to call the Repository yourself.

@smcvb Thanks,Waiting for your good news . :-)

Use the external Command Handlers , Because I want use the common service out of Aggregate.

such as

interface CommonService {

    fun currentTimeMillis(): Long

    fun generateIdentifier(): String


class UserCommandHandler(
        val repository: Repository<User>,
        val commonService:CommonService
) {

    fun handle(command: CreateUserCommand): String {
        repository.newInstance {
            User(userId = command.userId, time = commonService.currentTimeMillis())
        return command.userId


if I @Autowired In the Aggregate

class User {

    lateinit var userId: String

    lateinit var commonService:CommonService


    constructor(userId: String) {
        AggregateLifecycle.apply(UserCreatedEvent(userId = userId, time = commonService.currentTimeMillis()))

    fun on(event: UserCreatedEvent) {
        this.userId = event.userId


That will get error commonService not init ~
