Hi,
If the JPA validation mode is set to CALLBACK, BV constraints such as
@NotNull, @Size etc. are not reflected in the DDL created by ORM.
Instead, in TypeSafeActivator, the BV constraints are only considered for
DDL if the validation mode is DDL or AUTO [1].
CALLBACK is the safe way to ensure
I like it, but I think that's two separate concerns:
* using byte code generation to improve performance of entity instantiations
* avoiding the need for entities to have a parameterless constructor,
emphasising the mandatory properties of an entity (by requiring them as
constructor parameters)
