Get multiple entities by Id

I'm trying to fetch a list of entities, by their Id. I Use this query: SELECT c FROM User c WHERE c.id IN :ids This querey works as long as I don't set the property "id" as @Id. If i set @Id to any other member, this query works, if I set id as @Id, it stops working and gives zero results

When using inheritance, you can specify, which ID to use

When storing objects with inheritance, it should be possible to choose, which ID (parent or child class) should be used for new object. For example: public EntityA() {     @Id     long id;     String field1; }   public EntityB() extends EntityA() {     @Id     long id;     String field2
