can't render domain instance version field with jacksonJson?

we found that org.grails.compiler.gorm.GormEntityTransformation would forced to add @JsonIgnoreProperties(['version']) while ASTTransformation CompilePhase domain class in grails-data-mapping package.
Why it‘s so designed? How to bypass this limitation？How to output domain instance version filed with jsonformat?

Start with org.grails.compiler.gorm.GormEntityTransformation in the grails-data-mapping package and inspect the compile-phase handling that adds @JsonIgnoreProperties(['version']). Reproduce the domain instance serialization with jacksonJson, then determine what behavior is expected for the version field; done means the limitation is resolved or a supported bypass is documented and tested.
