NPE in JDTTreeBuilder.visit

[worblehat]

I get a NullPointerException when using spoon in no-classpath-mode to build a model of the following code:

public class Demo  {

    public foo() {
        A.B b = new A.B<C>() {
            D d = new D();
        };
    }
}

Exception in thread "main" java.lang.NullPointerException

@GerardPaligot be careful the method foo() does not have a return type (this is not the origin of the NPE).

The easy solution is to add if (scope != null) { at JDTTreeBuilder.java:2745

[worblehat]

the method foo() does not have a return type

Sorry, a typo.
