Questionable compilation failure

Hello there,

on my Windows 7 (64bit) box, the following does not compile with the developer preview build (b 106). Should it?

import java.util.function.Supplier;

public class SupplierTest {

    class Concrete<T> implements Supplier<Concrete<T>> {
        public Concrete<T> get() {
            return this;

    interface Test  {
        default void doSomething() {
             new Concrete<String>();   // <-----


The error message is:

\ error: non-static variable this cannot be referenced from a static context
new Concrete<String>();

However, a default method implementation is not static, or is it? (Perhaps it's just the error
message that's confusing me.)

n  Sebastian
