Summary: 
Accepting the hint "Use functional operation" to convert a for-each loop on a Collection works, but also causes the previous line with a comment to be deleted.

Steps to Reproduce:
[1] Create a trivial Java application exactly as follows:

package functiontest;
import java.util.Arrays;
import java.util.List;

public class FunctionTest {
    public static void main(String[] args) {
        List<String> strings = Arrays.asList("AAA", "BBB", "CCC");
        // for (String s : strings) { 
        for (String s : strings) { 
            System.out.println("Hello world " + s);
        }
    }
}

[2] There is a warning on the line with the for loop: "Can use functional operations".

[3] Press alt-enter on that line, then accept the hint to modify the code.

[4] An appropriate change is made, but the comment on the preceding line is also deleted.

Additional information: Bugs 241883 and 238887 look similar, but those problems relate to comment deletion for other hints.
