Steps to reproduce:

- Copy the code to the editor:
-----------------------------------------------------------
function f() {

    var seq = [1, 2, 3];

    for (n in seq) {
        println(n);
    }

    for (m in seq) {
        var n = m * m;
        println(n);
    }

}
-----------------------------------------------------------

- Refactor-> Rename the 'n' to 'n2' variable in 'for (n in seq) {' loop
  The 'n' variable is renamed in the second loop instead of the first

- Build the code

JavaFXApplication13\src\javafxapplication13\Main.fx:18: cannot find symbol
symbol  : variable n2
location: class javafxapplication13.Main
        println(n2);
