[ BUILD # : 200710071200 ]
[ JDK VERSION : 1.6.0_03 ]

Repro:
Create a new Java class. Add this method:
  public static void test() {
    FileInputStream fis = new FileInputStream(new File("."));
  }  

Use the editor hint to import java.io.File and then again to import
java.io.FileInputStream.

Result:

import java.io.File;

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
import java.io.FileInputStream;

/**

public class Test {
  public static void test() {
    FileInputStream fis = new FileInputStream(new File("."));
  }  
}


The 2 imports should be in subsequent lines, but one is above and the
other below the comment.
