Finite member variables make GC better?

This question is a continuation of this , but requires a more specific scenario.

Suppose we have the following class:

public class Person {
    private Foot left, right;

    public Person(Foot left, Foot right) {
        this.left = left;
        this.right = right;
    }
}

I was wondering if the next class could be optimized from the point of view of the GC if we turned it into the following:

public class Person {
    private final Foot left, right;

    public Person(Foot left, Foot right) {
        this.left = left;
        this.right = right;
    }
}

, , . , , GC ( ) , , Person . , Foot; .
