Annotation field validation	X	-	X	-

[*] Immutable types are not supported by Dozer. When a type doesn't have a no-arg constructor and all fields are final, Dozer can't perform the mapping. The workaround is introducing the Builder Pattern. An example can be found here [+] Requires a custom configuration
