What steps will reproduce the problem?

The following class does not compile under javac using lombok but it does on Eclipse. The problem seems to arise from mixing usage of @ val and @ Delegate in a parent-child relationship.

import lombok.Delegate; import lombok.val;

public class Main { public static void main(String[] args) { val bomb = new Bomb(); bomb.arm(); }

public static class Bomb { @ Delegate private Detonator detonator = new Detonator();

  private Timer timer = new Timer();

  public void arm()
  {
     this.timer.bomb = this;
     this.timer.start();
  }

}

public static class Detonator { public Trigger getTrigger() { return new Trigger(); } }

public static class Timer { private Bomb bomb;

  public void start()
  {
     val trigger = bomb.getTrigger();

     trigger.detonate();
  }

}

public static class Trigger { public void detonate() { System.out.println("BOOM!!"); } } }

What is the expected output? What do you see instead?

The error message returned is:

Main.java:46: error: Cannot use 'val' here because initializer expression does not have a representable type: Type cannot be resolved val something = parent.getSomething(); ^ 1 error

What version of the product are you using? On what operating system?

Lombok Version 1.12.2, JDK 7

The error should be

Main.java:40: error: Cannot use 'val' here because initializer expression does not have a representable type: Type cannot be resolved val trigger = bomb.getTrigger();

Confirming this is still an issue.
