Java 9, Spring Framework 5.0, Spring boot 2.0

Question

I am getting the following error when I upgrade from Java8 to Java9 Spring boot application. Is any annotation in the spring-web-5.0.0.RELEASE and spring-webmvc-5.0.0.RELEASE that are not supported by Java 9. I am unable to make out from the error received in the application.

Do you have this application working with Java 8 and it fails only when you're changing the Java version? — Stephane Nicoll, Oct 31 '17 at 19:41
Im excited to see this working with thymeleaf and I will surely migrate to j9 and boot2 — Antoniossss, Oct 31 '17 at 20:18
You may have a mixed version of dependencies or something broken/unusual in your build. Can you share a minimal sample that reproduces the issue? (Both Spring 5 and Spring Boot 2 are fine with Java 9 and this exception is unrelated to the change of JDK as far as I know) — Stephane Nicoll, Nov 01 '17 at 06:28
I found the same problem in [this](https://github.com/spring-projects/spring-boot/issues/4579) issue on github. Make sure that you are not facing the same problem. Otherwise please provide additional information regarding your issue. — Anastasios Vlasopoulos, Nov 04 '17 at 17:35

If you see this other ticket sun.reflect.annotation.TypeNotPresentExceptionProxy exception after adding EntityListeners

The exception that you´re having TypeNotPresentExceptionProxy it could be you have an annotation which a class that is not in the classPath.

On of the greatest/annoying features of Java 9 is the module system, where now you will have to specify in your module-info some package if you want to use it.

Your requestMappingHandlerMapping class contains any annotation that can prove my theory?

The "RequestMappingHandlerMapping" from the Spring MVC class is a annotation by itself. — SSNM, Nov 03 '17 at 19:43
