Hi @thombergs,
I was taking a look at the implementation of the SendMoneyService (https://github.com/thombergs/buckpal/blob/master/src/main/java/io/reflectoring/buckpal/account/application/service/SendMoneyService.java).
It seems you are implementing pessimistic locking by explicitly locking the banck accounts with the AccountLock.
I can see that you also handle the transaction (either commit/rollback) with javax's Transactional.
Given that the locks on the bank accounts are released before the transaction is committed/rollback, how can you make sure that in between (ie, when the locks are released but before the commit/rollback is done) there's not another transaction executed with the same bank accounts before this one is fully finished?
Thanks
