    Can't use class name "Group" for an entity

      If I have this entity:

       

      @Entity
public class Group {

  long id;

  @Id
  public long getId() {
  return id;
  }


  public void setId(long id) {
  this.id = id;
  }
}

       

      I get this error on stratup:

      If I change the class name from Group to something else like Groupe the error disappears. Seems like a bug to me, is that so?
