Regression in wording of unchecked warning message

Compile this program with -Xlint:unchecked
import java.util.*;
class mc {
    public static void quicksort(Vector vector, Comparator compare)
    {
        Collections.sort(vector,compare);
    }
}

jdk8b42 javac outputs this warning (among others):
mc.java:5: warning: [unchecked] unchecked conversion
        Collections.sort(vector,compare);
                         ^
  required: List<T>
  found: Vector
  where T is a type-variable:

jdk8b43 javac outputs this warning which is less accurate:
mc.java:5: warning: [unchecked] unchecked conversion
        Collections.sort(vector,compare);
                         ^
  required: List<Object>
  found: Vector
