Lambda functions take few seconds at runtime to execute

[johnmeshulam]

When passed as a parameter for Wait.waitFor() or Parallel.doAction(), lambda functions will block for a good few seconds at runtime:

System.out.println("Before");
Parallel.doAction( () -> {
    System.out.println("While");
});
System.out.println("After");

The delay betweek "Before" and "While" is a few seconds long.

Writing the implementation of the Functional Interface fixes this issue:

System.out.println("Before");

Action a = new Action() {
    @Override
    public void execute() {
        System.out.println("While");
    }
};

Parallel.doAction(a);

System.out.println("After");

The delay between "Before" and "While" is unnoticeable.
