A DESCRIPTION OF THE PROBLEM :
HashSet containsAll method returning true for empty set values
Example:

Set<Long> first=new HashSet<>();
        first.add(2L);

        Set<Long> second=new HashSet<>();
        first.containsAll(second) -->true;
comparing an empty list with a list which has values returning true,which should return false.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
false

---------- BEGIN SOURCE ----------
import java.util.HashSet;
import java.util.Set;

public class Test2 {

    public static void main(String[] args){
        Set<Long> first=new HashSet<>();
        first.add(2L);

        Set<Long> second=new HashSet<>();
        first.containsAll(second);
        System.out.println(first.containsAll(second));

    }
}
---------- END SOURCE ----------

FREQUENCY : always
