Please find attached project as a test case (although the project is not in the format which you had specified). I think I have more clarity on the root cause of the exception and it lies in the behavior of spring.jpa.properties.hibernate.hbm2ddl.auto = validate which is equivalent of hibernate.hbm2ddl.auto = validate in hibernate. For version 5.3.x, Hibernate throws no validation exception but for version 5.4.x CR1 exception is throws as org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: missing sequence |
