Spring JPA - @OneToMany create separate tables per relation

I want to create type called 

@Entity
class TestType {
   @Id
   private Long id;
   private String field1;
   private String field2;
}

@Entity
class Agregator{
   @Id
   private Long id;
   private String name;
   @OneToMany
   private List<TestType> newTypes;
   @OneToMany
   private List<TestType> oldTypes;
}

and I want to have 3 tables:

How I need to define relation to get such tables and columns ?

@Embeddable
class TestType {
   @Id
   private Long id;
   private String field1;
   private String field2;
}

@Entity
class Agregator{
   @Id
   private Long id;
   private String name;
   @ElementCollection
   private List<TestType> newTypes;
   @ElementCollection
   private List<TestType> oldTypes;
}
