    The fields of a record are final, so they must be set through the constructor. Many frameworks will cheat and use various tricks to modify final fields after the fact anyway, but these will not work on records. If you want to instantiate a record, you have to provide all the field values at construction time.

    It may take a little time for frameworks to learn about records. The old model of "call a no-arg constructor, then set the fields" will not work for records. Some frameworks are already able to deal with this (e.g., "constructor injection"), while others are not yet there. But, we expect that frameworks will get there soon enough.

    As the commenters said, you should encourage your framework provider to support them. It isn't hard.
