Eager fetch performed for OneToOne association in Hibernate

Issue

• Two classes have been defined with a OneToOne association between them

  @Entity
  public class Employee {
      ...
      @OneToOne(mappedBy = "employee")
      private Task task;
      ...
  }
  
  @Entity
  public class Task {
      ...
      @OneToOne
      @JoinColumn(name = "employee_name")
      private Employee employee;
      ...
  }
  

• When the side that does not own the foreign key is loaded from the database (e.g. an "employee"), the side which owns the foreign key (e.g. "a task") is (eagerly) fetched from the database even if it is not directly referenced by the HQL query or otherwise explicitly accessed.
