Used the following code to reproduce, but was not able to:

public class TestIteratorRendering {
public static void main(String[] args) {
List<String> list = new ArrayList<String>();
list.add("one");
list.add("two");
list.add("three");
Iterator<String> iterator = list.iterator();
while (iterator.hasNext()) { // breakpoint here
String str = iterator.next();
System.out.println(str);
}
}
}


Could you give an example in which the "iterator.next()" expression is auto-created?

Nevermind, reproduced.
This is true for expressions like this: "Data data = iterator.next().getData()"
As a workaround please use ExtractVariable refactoring:

MyObject obj = iterator.next();
Data data = obj.getData();
