Runtime error. java.lang.NoClassDefFoundError: java/util/functions/Predicate

[José Luis Garbi]

Hello everyone,

I'm new to Project Lambda and I'm giving it a try.
I installed 1.8.0-ea-b59 (Win 64 bits)
When compiling; I get no errors.
When executing; I get an error: Exception in thread "main"
java.lang.NoClassDefFoundError: java/util/functions/Predicate

Could you please give me some advice? (sorry if it's too basic)

*The class definition*

import java.util.ArrayList;
import java.util.List;

public class ProjectLambdaMain {
 public static void main(String...  args) {
  List<Character> lc = new ArrayList<Character>();
  lc.add('a');
  lc.add('b');
  lc.add('d');
  lc.add('1');
  lc.add('2');
  Iterable<Character> filteredCharList = lc.filter(c ->
Character.isAlphabetic(c));
  }
}

*The error*
