hibernate - JPA @MappedSuperclass and JPAMetaModelEntityProcessor -

i have following scenario:

1) abstract @mappedsuperclass composite pk:

@mappedsuperclass @equalsandhashcode(of = { "id" }, callsuper = false) public abstract class localizeddetail {      private static final long serialversionuid = 1l;      @embeddedid     @getter     @setter     private localepk id; (...) 

2) pk:

@embeddable @equalsandhashcode @allargsconstructor @noargsconstructor public class localepk implements serializable {      private static final long serialversionuid = 1l;      @column(name = "id", length = 256)     @getter     @setter     private string id;      @column(name = "locale", length = 16)     @getter     @setter     private string locale;  } 

3) localizeddetail sub class:

@entity @table(name = "bt_value_object_info") public class valueobjectinfo extends localizeddetail { (...) 

4) generating jpa meta model through maven using org.hibernate.jpamodelgen.jpametamodelentityprocessor plugin.

what happening localepk metamodel being generated without attributes:

@generated(value = "org.hibernate.jpamodelgen.jpametamodelentityprocessor") @staticmetamodel(localepk.class) public abstract class localepk_ {   } 

but if set localepk composite pk of other entity not extends localizeddetail generated correctly. need create "fake" entity class generate metamodel.

is there known limitation model generate correct pk meta-model?

thanks,
