Here is a simple test:

import java.awt.*;
import java.awt.Color;

public class Main {
    public static void main(String[] args) {
        System.out.println(Color.RED);
        System.out.println(BorderLayout.NORTH);
    }
}

if you run "fix imports" it changes nothing, however we definitely have 
redundant import here :( Note, that "fix imports" handles duplicated single 
(or .*) imports correctly.
