Is this an optimization ?

Question

env : jdk 5 or 6
import java.util.ArrayList;
import java.util.List;
public class Test {
     public void method(){
               List<Object> list = dao.getSomeData();
               for(Object obj: list){
                    doSomething(obj);
                    obj = null;//Here optimization
          public void doSomething(Object obj){
               //do something with computation based on object 'obj'
}thanks

which makes it the reverse of an optimisation as you're now using a few more CPU cycles for every iteration through the List (unless of course the compiler is smart enough to remove the entire null assignment because it has no effect whatsoever).Wouldn't an optimizing compiler remove the unnecessary assignment?
