RFR: 7113349 JDK8 port to macosx

[Henri Gomez]

Well, I tried some Java 8 samples like :

public class Sample4 {

  enum Decision {
    APPROVE, DECLINE, APPROVE_REFER
  }

  interface DecisionService {
    Decision getRiskDecision(Applicant applicant);
  }

  class Applicant {
    private int score;

    public Applicant(int score) {
      this.score = score;
    }

    public int getScore() {
      return score;
    }
  }

  public void test() {
    DecisionService cs = (a) -> {
    if (a.getScore() > 700) {
      return Decision.APPROVE;
    } else if (a.getScore() > 600 && a.getScore() < 650) {
      return Decision.APPROVE_REFER;
    } else {
      return Decision.DECLINE;
    }};
    Decision decision = cs.getRiskDecision(new Applicant(800));
    System.out.println(decision.toString());
  }

  public static void main(String... args) {
    new Sample4().test();
  }
}

But it fail to build ;(

Sample4.java:24: error: lambda expressions are not supported in -source 1.8
   DecisionService cs = (a) -> {
                            ^
 (use -source 8 or higher to enable lambda expressions)

Tried to force -source 8, no more luck.

Any Lamba guru around ? :)
