Summary 
=======
When using Refactor => Move to relocate a method to another class, the return type of that method is changed from List<String> to List.


Steps to reproduce
==================
[1] Create a trivial Java application named TestRefactorMove with two classes in file TestRefactorMove.java as follows:

package testrefactormove;
import java.util.ArrayList;
import java.util.List;

public class TestRefactorMove {
    public static void main(String[] args) {
        List<String> list1 = new ArrayList<>();
        list1.add("AAA");
        list1.add("BBB");
        List<String> list2 = lowerMembers(list1);
        System.out.println("Before: " + list1.toString());
        System.out.println("After:  " + list2.toString());
    }

    public static List<String> lowerMembers(List<String> list) {
        List<String> lower = new ArrayList<>();
        for (String s : list) {
            lower.add(s.toLowerCase());
        }
        return lower;
    }
}    

class SomethingElse {
}

[2] Build and run the app to verify that it works.

[3] Place the cursor on the static method named "lowerMembers", right-click, then select Refactor => Move.

[4] In the "Move Members" dialog select "SomethingElse" from the "To class" drop list, then click the "Refactor" button.

[5] The method is moved, but note that the return type of the moved method SomethingElse.lowerMembers() has been changed from "List<String>" to a raw "List". This example moves a static method, but the problem can be reproduced with non-static methods.
