Reformat on save does not fix invalid indentation in following case:

1) turn on Reformat modified lines on save
2) have a code:
    public static void main(String[] args) {
        MyList<String> c = new MyList<String>();
        c.add("aaaa");
        System.out.println("");
    }

3) put caret on the begging of the text on line 'c.add'
4) press backspace several times
5) save the file
-> the line is not move to correct indentation level and stays as it is
(does not matter if you move cursor to another line before saving)

Interesting is that if the line is moved to invalid position by space the reformat works fine
