Don't try to unmarshal void return types when there are out parameters being returned.

    // The return value

    {

        Type* t = NAMES.Search(method->type.type.data);

        if (t != VOID_TYPE) {

            Variable* rv = new Variable(t, "rv");

            dispatchMethod->statements->Add(new VariableDeclaration(rv));

            generate_create_from_data(t, dispatchMethod->statements, "_result", rv,

                    resultData, &classLoader);

            realCall->arguments.push_back(rv);

        }

    }

    VariableFactory stubArgs("arg");

    arg = method->args;
