This is because the / (divide) operation is used. When set as @Transactional(timeout=1), {code:java}(Timeout upper limit date and time - Transaction end date and time) / 1000{code} is always 0 (zero). !3 (0e92237d-95aa-42dd-873c-fb13416d9bc1).png|width=643,height=1280! Therefore, TransactionException is always caused by the following logic. {code:java}if (secondsRemaining <= 0) { throw new TransactionException( "transaction timeout expired" ); }{code} I am considering this as a bug, so I suggest to fix the code as below. {code:java}if (secondsRemaining < 0) { throw new TransactionException( "transaction timeout expired" ); }{code} If necessary, I will please refer to my PR.
