Description Sven Efftinge

2014-06-16 04:17:49 EDT

@Data suffers from the "renaming field problem" (i.e. bug #382914) which renders it useless for deserialization frameworks which set the fields (e.g. JPA, Hibernate, GSON ...). Also we cannot change @Data as it would break existing code.

A new annotation for value objects should be introduced. We could implement the contract described in [1]. Also the name ValJO is nice, though @ValueObject might be more readable.

[1] - http://blog.joda.org/2014/03/valjos-value-java-objects.html

To avoid further miss use of @Data (or @ValueObject) I have files bug #437508. This means that @ValueObject could and should be more strict with respect to immutability.
