Filter a filled Set with filter and a lambda does not work

In Program:

import java.util.stream.*;
import java.util.*;

public class PQL {
    public static void main(String[] args) {
        Set<Integer> y = new HashSet<Integer>();
        y.add(5);
        y = y.stream().filter(c -> c < 3).collect(Collectors.toSet());

    }

}

Expected result: Execute without error.

Actual result:

Exception in thread "main" java.lang.AbstractMethodError: Method PQL$1.test(Ljava/lang/Object;)Z is abstract
