wish of those help That would lead to a StackOverflowError : bar calls combine, which calls bar, which calls combine...
You need to recursively refer to sc in its definition (you can't use this in a lambda to refer to the object being created by the lambda). I believe that is only possible in an instance or class variable. So it could look like:
code :
public interface StringCombiner {
    String combine(String s1, String s2);
    default String bar(String s1, String s2) { return "bar"; }

//Note: you need the static block to avoid a "self-reference" compilation error
static StringCombiner sc;
static {
  sc = (s1, s2) -> sc.bar(s1, s2) + s1 + s2;

public static void main(String[] args) {
    System.out.println(sc.combine("a", "b"));

I wish did fix the issue. You don't need the outer lambda in C#, it can be replaced by a simple block.
Directly invoking a lambda is a workaround for the lack of block level variables in Javascript (new versions support block scope using let).
code :
Func<int> counter;

     int n = 0;
     counter = () => n++;

I hope this helps . This is probably intentional so you don't get parameter blocks disappearing on you:
code :
def foo(x: Int = 2)(y: Int = 4) = x*y

foo(3)    // What does this mean???

it fixes the issue
I noticed that lambdas both work using function pointers as well as the dedicated function type
code :
template <typename Function>
int apply(Function && f, int a, int b) {
     return f(a,b);

hop of those help? It was the warmer (Node) lambda going haywire, even though all the logs pointed at the worker (Python) lambdas. After setting context.callbackWaitsForEmptyEventLoop = false, the problem disappeared.

seems to work fine To give you an example take the case of the Collection.forEach method, which is designed to take an instance of the Consumer functional interface and has a default implementation in the Collection interface:
code :
default void forEach(Consumer<? super T> action) {
    for (T t : this) {
