hibernate.ddl.auto doesn't meet the documentation

Documentation [1], when preparing for production says:
>>So we will let Hibernate create the database schema if it doesn’t exist, but it will never update it automatically.
>>Change the jpa.ddl configuration key:
>>
>>%server01.jpa.ddl=create

But when I do, the schema id being dropped every time Play! app starts.
update and none options works as expected.
Play! 1.0.1, MySQL
