This looks like an artifact of devserver automatically adding old servlets and trying to initialize them, even though GuiceFilter would never delegate to them. You can workaround this for now by setting an empty servlet bound to /_ah/api/*.

I added an empty servlet, it worked correctly. Thanks.

@WebServlet(name = "empty", value = "/_ah/api/*")
public class EmptyServlet extends HttpServlet {}
