Vaadin with SpringBoot

HI 

I am using Spring Boot 1.4.0.RELEASE and Vaadin 7.6.5
I am trying to open a jsp page as wel come file. for doing this i SpringBoot i need the following dependency.

<dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <scope>provided</scope>
</dependency>

When i add this dependency its working fine showing the jsp files but with the following error.

2016-10-20 18:41:10.167  WARN 3392 --- [ost-startStop-1] o.a.tomcat.util.scan.StandardJarScanner  : Failed to scan [file:/C:/Users/vega/.m2/repository/com/vaadin/vaadin-sass-compiler/0.9.13/sac-1.3.jar] from classloader hierarchy

java.io.FileNotFoundException: C:\Users\vega\.m2\repository\com\vaadin\vaadin-sass-compiler\0.9.13\sac-1.3.jar (The system cannot find the file specified)

Mark H.: Problem relates to the Tomcat version used by Spring boot. See 
https://github.com/spring-projects/spring-boot/issues/6657 for more info.

As the solution simply downgrade the Tomcat version used by Spring in your pom.xml file:

<properties>
<tomcat.version>8.0.32</tomcat.version>
</properties>

This is the best solution . Although the error did nothing but i still want to remove it and this is the solution
