Spent 2 hours on this today. My service method throws a custom checked exception after saving an entity, and the save is NOT rolled back. ```java @Transactional public void createInvoice(...) throws InvoiceException { repo.save(invoice); if (bad) throw new InvoiceException("..."); } ``` Is this expected? Feels like a bug.
