Description

When calling an association property from the object itself, null is associated with the object and this leads to NPE or unwanted results.
For example, if I have a class :
public class Person {
private Long id;
private String firstName;
private String lastName;
private Person parent;
public Person getAncestor() {
if (getParent() == null)

{ return this; }

else

{ return getParent().getAncestor(); }

}
//Other getters and setters.
}

And a method calls person.getAncestor(), this.getParent() inside getAncestor() method will return null.
But if the method calls person.getParent() and then person.getAncestor(), this.getParent() inside getAncestor() method will return the expected parent.
