The following test source was used:
@RequestScoped
public class BackendService {
public double average() {
List<Integer> numbers = new ArrayList<>();
numbers.add(42);
numbers.add(21);
numbers.add(7);
return numbers.stream().mapToInt(i -> i).average().getAsDouble();
}
}
However, GlassFish v4.0.1 nightly builds builds starting with March, 20th 2014 supports Java 8 and lambdas. You can deploy Java EE 7 applications running on Java 8 with lambdas.
See you at Java EE Workshops at MUC Airport!
